    <p>In recent years, research and development of highly accurate position detection indoors have attracted attention. In this paper, we propose a new scheme to improve accuracy of position detection indoors, identifying the direct wave between BLE transmitter (TX) and BLE receiver (RX), applying RD-CUBA-MUSIC<sup>(1)</sup> to indoor multi-path environment. In the proposed scheme, the direction of radio wave arrival is estimated in both directions of TX→RX and RX→TX. Estimation accuracy is improved by collating the arrival directions of the pair of two-way direct wave candidates. This Direction-Of-Arrival (DOA) estimation for direct wave is sequentially executed with a plurality of RXs and indoor position of TX is detected using the DOAs and the corresponding RX positions. In RD-CUBA-MUSIC, we select a beam pattern with high correlation with the sinc function beam pattern as a beam pattern of the ESPAR antenna. Computer simulation shows that the proposed scheme can achieve a detection accuracy within 1 m in error at a 91% probability. It also shows within 0.5 m in error at 67% even though it is in an indoor multi-path environment.</p>

    Circular synthetic aperture radar (CSAR) is an imaging technique of which the radar trajectory takes a circular form, and the antenna beam illuminates the center of the circular path to acquire the backscattering of targets. Comparing to the SAR systems which have a linear trajectory such as stripmap SAR or spotlight SAR, CSAR has an advantage of being able to image the radar cross section (RCS) of the targets from various azimuthal angles to obtain the high-resolution image. In this report, a simple preprocessing scheme for CSAR received data, called the wire structure intensifier (WSI), is proposed to enhance the scattering from a wire-like target. To demonstrate the proposed method, CSAR experiments are carried out in an anechoic chamber.

    In PolSAR data utilization, it is important to precisely detect urban areas, not only for monitoring the effect of urbanization but also for detecting the stricken residential buildings immediately after a big disaster. In order to improve the accuracy of the detection, it is required to reveal scattering characteristics of urban areas in detail. This paper reports empirical findings from polarimetric scattering measurement for simplified man-made structure models. It is found from the measurement data analysis that both squint and incident angles have strong effect on some polarimetric indices. We also discuss the relationship between the size of the model and its polarization features.

    In recent years, several indoor intrusion/event detection methods using radio propagation change caused by intruder have been proposed. One of the indoor intrusion/event detection methods with an array antenna can detect intrusion/event using receiving signal eigenvector change. In addition, the method intrusion/event detection method using MIMO channel change also has been proposed. However, these reports have not discussed intruder location detection. In this report, we consider possibility of indoor intrusion/location detection by the computer simulations.

  • Data Symbol Reduction for Blind MIMO Transmission by using ICA

    In the MIMO system, transmitted streams are multiplexed spatially at the same frequency. This causes inter-stream interference at the receiver. Therefore, equalization/decoding method is necessary. Least Squares Channel Estimation (LSCE) is often used as the method. However, overhead of throughput due to training symbols is a problem for effective transmission. In this report, we employ on Independent Component Analysis (ICA) as a blind method without the training symbols. We have reported effectiveness of the ICA with a small number of training symbols compared with that of the LSCE. However, since the ICA is statistical channel estimation method, many data symbols are often needed. In this report, we propose to apply a pre-filtering processing to the transmitting signals to obtain better performance compared with the conventional ICA. Computer simulation results are shown to demonstrate availability of the method. Furthermore we provide some experimental results to show the effectiveness of proposed method in the real environment.

    Recently, space-time adaptive processing (STAP) and multiple-input multiple-output (MIMO) have been applied for the suppression of clutter in airborne radar systems. Multipath clutter located closely to targets can be suppressed by using the MIMO-STAP technique. Generally, the maximum signal-to-noise ratio (MSN) method is often used in radar systems using the STAP or MIMO. Increase in degrees-of-freedom (DOF) to improve target detection performance yields many training data and a inverse matrix calculation of higher order, and as a result the calculation becomes difficult in real time. To solve such problems, the multistage Wiener filter (MWF) method is applied, which needs fewer training data than the MSN method. In this report, we have evaluated performance of the MIMO-STAP using the MWF by computer simulations.

    Polarimetric scattering characteristics of targets depends on incidence angle, frequency, polarization, and resolution. To understand these characteristics of targets, a variety of target classification methods are used. This report presents polarimetirc scattering characteristics in the Ku-band about models of buildings assumed urban areas. Polarimetric scattering characteristics of targets in the Ku-band is expected to be one of the key features as next generation airborne and satellite SAR application. A laboratory experiment using four-component decomposition of polarimetric scattering characteristics with Ku-band POLSAR supported the theoretical result.

  • Polarimetric Scattering From Simplified Boundary Model Between Water And Emerged-plants Areas In Wetland

    This paper examines the validity of a simple water area classification method based on POLSAR image analysis, by considering the result of the FDTD polarimetric scattering analysis for a simplified water-emergent boundary model. The present classification method, which was proposed in our previous study, is realized by extracting the strong double-bounce scattering components generated from the water-emergent boundary when the water level is relatively high. However, it has not been cleared whether or not the polarimetric scattering feature is dependent on the variation of the emergent's biomass and/or the radar illumination angle. In this paper, by executing the FDTD analysis for the simplified water-emergent boundary model, we examine the polarimetric scattering mechanism around the wetland boundary regions. It is resultantly confirmed from the FDTD result that the strong double-bounce scattering can be observed even when the biomass and illumination angle are both small.

    We have developed a fully polarimetric FM-CW Radar system that can acquire scattering matrix almost simultaneously in time. Conventional polarimetric radar transmits, for example, H-polarized wave and receives H-and V-polarized signals. Then the radar transmits V-polarized wave and receives the H-and V-polarized signals. Therefore the radar switches transmitting polarization H and V, alternatively, which causes a small time-delay between H and V. The delay sometimes causes adverse phase error in scattering matrix. It is desirable to make the delay as small as possible to acquire scattering matrix simultaneously. We have devised to cut the delay by using delay-line for simultaneous scattering matrix acquisition. The delay-line type FM-CW radar was found to be effective in the simultaneous acquisition. A laboratory experiment using four-component decomposition of scattering mechanism supported the advantage of the system.

    A digital beamforming(DBF) array with adaptive beamforming has limitation that circuit scale and power consumption increase with the number of array elements. In order to circumvent this problem, multiport parastic array radiator(MuPAR) antenna have been proposed. We applied the steepest gradient algorithm (SGA) to optimize the reactances, and applied RLS algorithm to perform DBF at the active elements. We compared adaptive beamforming performance with DBF array. However, the convergence speed is very slow. In this report, We propose a modified fast convergence scheme of adaptive beamforming with the MuPAR antenna. Performance of adaptive beamforming with the MuPAR antenna is examined by the computer simulation.

    This report presents a coherent decomposition scheme for high resolution polarimetric SAR data. This coherent decomposition here implies that the decomposition is applied to a single or a few scattering matrix data. Based on the polarimetric scattering matrix data obtained by an FM-CW ROLSAR system, we have devised a simple decomposition technique using the coherency matrix for purpose of identification of scatterer. This report presents a brief description of the decomposition method and some experimental results. It is shown the scattering mechanisms are well recovered and the orientation angle of wire target are precisely measured.

    Classification of terrain is one of the most important applications of Polarimetric Synthetic Aperture Radar (POLSAR) image analysis. This paper presents a simple method to classify terrain by the use of the correlation coefficients in the circular polarization basis together with the total power of the scattering matrix in the X-band. The reflection symmetry condition that the co-polarized and the cross-polarized correlations are close to zero for natural distributed scatterers is utilized to extract characteristic parameters of small forests or cluster of trees, and oriented urban building blocks in dependence of the direction of the radar illumination. Both of these kinds of scatterers are difficult to be identified in high resolution POLSAR images of complex urban areas. The indices employed here are the correlation coefficient, a modified coefficient normalized by the reflection symmetric conditional case, and the total power. It is shown that forest areas and oriented building blocks are so easily detected and identified. Then terrain is classified by these-combinations showing the result is corresponding well to the photographic ground truth images.

    Recently, applications of high-resolution Direction-of-Arrival (DOA) estimation with an array have been increasing including position estimation in smart antenna and RF-ID system. To realize high-resolution capability, superresolution technique such as MUSIC algorithm is often adopted. However, precise array calibration is necessary to realize essential performance of the algorithm. In this report, we propose a new simple calibration technique based on impedance matrix of the array. In this technique, number of adjusted parameters or unknowns becomes only one for uniform array. Performance of the proposed technique is verified by the computer simulations.

    Four-component decomposition scheme is developed for polarimetric SAR image analysis based on coherency matrix. The coherency matrix is used to deal with non-reflection symmetric scattering case, which is an extension of covariance matrix approach. The same decomposition results have been obtained. The advantage of this approach is explicit expressions of 4 scattering powers in terms of scattering matrix elements, which serves interpretation of POLSAR data quantitatively.

    The off-nadir angle of space-borne or air-borne SAR is set typically 20 - 60 degrees. Flat surface area such as sea or ground reflects the incident wave into specular directions, thus leading to small backscattering to the radar. The acquisition of data in such flat area is one of radar applications. Bistatic radar is designed to accommodate to the situation, however, large space is mandatory for bistatic measurement. In this report, we present a bistatic measurement method using dihedral corner structure to acquire specular reflections. Scattering matrix measurement was carried out in anechoic chamber for the evaluation of lossy dielectrics and for derivation of complex permittivity. It is shown that this method is effective for bistatic measurement in limited space of anechoic chamber.

    Polarimetric SAR provides scattering matrix of ground surface. This report presents polarimetric scattering characteristics of dielectric corner reflectors. One of typical targets is urban area where building wall and road construct dihedral corner reflectors. Scattering characteristics from typical structure is the main topic of this report. In the analysis, we employed FDTD method to derive scattering matrix for oriented structure with respect to radar line of sight.

    Recently, superresolution techniques have become indispensable methods for various problems. However, it is often difficult to apply the superresolution techniques in real DOA estimation system because of some error factors. Thus, we should apply array calibration. In this report, we show array calibration effects by numerical simulation with NEC2 and some experimental results to verify the performance improvement with the array calibration.

    Language:Japanese   Publisher:The Institute of Image Information and Television Engineers  

    Recently, researches for direction-of-arrival(DOA)estimation using antenna array have made great progress. Especially, it is desired for the estimation by superresolution techniques to apply to communication systems as well as sensings. However, implementation of perfect antenna array which ofen appears in formulation of superresolution techniques is impossible and must supplement it by calibration of antenna array before appling superresolution technique. In this report, we propose a calibration-parameter estimation method for antenna array that utilized wave sources whose DOAs are already known. The main improvement in this method is reduction of number of data sets for calibration.

    Recently, use of Polarimetric Synthetic Aperture Radar (POL-SAR) has become indispensable tool for terrain observation, classification and disaster surveillance. In this report, as a basic research, we aimed at figuring out the polarimetric scattering characteristics of buildings. We measured scattering matrices of miniature model of buildings in a laboratory using a step frequency radar (Network Analyzer). To examine scattering characteristics of the building, we decomposed this scattering matrix into three components (properties of sphere, diplane, helix) and three components scattering power (surface scattering, double bounce, volume scattering). The percentages of each component from the scattering matrix of building are shown in this report.

    Superresolution techniques have been widely noticed as high-resolution direction-of-arrival methods for wave propagation analysis in mobile communication. Generally, the technique that can revolve multipath waves is applied only to uniform array, and its resolution depends on the array length. Weiss et al. reported a interpolated array techniques which leads to the virtual array having long array length. In this report, we evaluate convergence property of the method by computer simulations, and propose a improved technique. Also, estimation errors of the method are evaluated.

    Recently, in the Direction-of-arrival (DOA) estimation with an antenna array, superresolution techniques have become attracting methods because of its high resolution capability of resolving incoming waves. One of its method called MODE method can resolve coherent signals directly. However, the method is only applicable to uniform linear array. In this paper, we propose to apply MODE method with EM (Expectation Maximization) algorithm to DOA estimation of coherent signals in nonuniform array. Simulations and experimental results show that the proposed method is valid in this case.

  • An Improvement and Performance Evaluation of T-bar Fed Slot Antenna Using Subsurface Radar

    A T-bar fed slot antenna designed for subsurface radar has wide band and flat frequency characteristic. The antenna can operate from 250 MHz to 1000 MHz (where VSWR < 3). However, the antenna can not provide optimal performance for radar system without a proper matching circuit, because of an impedance mismatching between a radar circuit of 50 Ω and the antenna of 150 Ω. Therefore a radar image is degrade by reflected wave on input port of the antenna. In this paper, an impedance matching technique of the antenna is discussed. The impedance matching between a radar circuit and the antenna can be attained by optimizing the T-bar shape. As a result, flat frequency characteristic of VSWR < 2 over 350 MHz ∼ 1000 MHz is obtained.

    This rcport describes the polarimetric scattering charactcristics of multiple targets aligned in the range direction within a radar resolution. Since radar target such as terrain extends both in the range and in the along-track dirction, the backscattered wave undergoes multiple reflections. The problem in polarimetric radar is how to evaluate such a scattering matrix resultant from multiple reflected waves. This report examines the fundamental polarimetric scattering characteristics of multiple wires. The scattering matrices of composite wire are derived as a function of thei spacing, simulated by the FD-TD analysis, and then compared to the experimental data. It is shown that resultant scattering matrix changes with spacing and that the interpretation of scattering matrix by multiple target becomes difficult.

    This paper proposes a numerical method-a method of cross iteration for obtaining the optimum contrast polarization states of the transmitter and receiver in the incoherent case, based on the formula of the optimum contrast polarization state in the matched-pol channel.Then the proposed algorithm is proved as convergent and is very easy for programming. Finally, we give two examples. The result of the first example is completely identical with Ioannidis', showing the validity of the presented method. From the second example, one can find that if the receiving polarization state is independent of the transmitting's, the power ratio may be much larger than those in the cases of the co-pol channel, cross-pol channel and the matched channel, showing the importance of the considered model.

    Sinclair scattering matrix plays a decisive role in radar polarimetry. For a realization of real time and full polarimetric radar system, there are several technical problems associated with hardware imptementations. We modified an FM-CW radar to a real-time system by adding a PIN diode switching circuit for antenna polarizations. In this report, we present the hardware design of the radar and show some preleminary experimental decomposition results of targets using the system.

    Huynen has provided a method to decompose a Mueller matrix into an average single target and a N-target (non-symmetric target and noises) in order to retrieve detailed target information. However, the decomposition sometimes fails in the presence of small error or noise in the elements of Mueller matrix. This paper attempts to improve Huynen's decomposition method. First, the definition of a stable decomposition is given, showing the importance and a problem of Huynen's approach by an example. Then a method is proposed to carry out stable decomposition, based on the Least Squares Method and the Newton's Method. Stability means the decomposition is not sensitive to errors. The proposed methods overcomes the problems on the unstable decomposition of Mueller matrix. Finally, two numerical examples are given, showing our method is superior to the methods of Huynen and Pottier.

    The high-resolution capability of the superresolotion technique is available for analyzing the local mechanisms' of the electromagnetic scattering waves. In this paper, we apply the modified Root-MUSIC algorithm to the back scattering wave from the circular aperture of a cylindrical waveguide that contains frequency dispersive waves. Especially, we consider two types of SSP schemes, a pre- and a post-SSP techniques, for the modified Root-MUSIC algorithm, and show that the post-processing technique is stable. Furthermore, we show availability of a time-domain notch filtering scheme for the improvement of the estimation accuracy. In addition numerical and experimental results are shown to verify these results.

    Recently, estimation and resolution improvements utilizing the polarization information of electromagnetic wave have been attracting attention in the remote sensing and the indoor radio propagation analysis. Several modifications using the polarization gata have reported in superresolution techniques. In this paper, we propose a new modification concerning with decorrelation preprocessings for the technique. The method has two main advantages compared with the conventional one; 1)improved decorrelation performance, 2)increased the number of resolvable signals. The resolution improvement is achieved theoretically and experimentally.

    In recent years, various subsurface radars have been investigated. The requirement for subsurface radar is the ability of high resolution and the detection of deep objects in underground. Therefore, the radar must use high power with wide-band spectrum. However, the wave radiated from the radar does not necessarily penetrate into underground, resulting is undesired radiation into the free space. In order to detect deep objects and reduce undesired radiation to free space, this report discusses the position and structure of horn antenna based on the FD-TD method.

    Massive MIMO enables the improvement on the transmission rate without increasing the burden on the signal processing by employing a large number of antennas at a base station (BS). Channel state information (CSI) feedback scheme from terminal stations to BS gives a very large overhead when considering massive MIMO and implicit beamforming (IBF) with the calibration technique as the countermeasures are introduced. However, it is reported that CSI estimation itself has a large overhead when considering massive MIMO. In this report, we propose analog-digital hybrid configuration using analog multi-beams and blind algorithm called Constant Modulus Algorithm (CMA) which does not need the CSI estimation. Via a computer simulation, the effectiveness of proposed configuration is verified.

    For many Asian countries, a rice crop monitoring plays a key role to realize stable food supply. Because of its flexible operability with wide swath, SAR remote sensing has been attractive as an efficient monitoring tool. Though the SAR data analysis for rice crop monitoring has been intensively studied, it still has non-negligible mysteries due to its difficulty to link the radar signature to specific physical parameters such as a growth situation. To solve the problems, it is essential to conduct theoretical characterization of experimentally obtained radar backscatter from rice paddies. In this paper, the rice paddies were observed by a high resolution X-band SAR, Polarimetric and Interferometric SAR 2 (Pi-SAR2), by systematically varying the observation parameters such as incidence angle and polarization. The obtained features based on many sample points in Niigata city indicate that the dominant scattering mechanisms are gradually varied in terms of incidence angles.

    In the electromagnetic wave scattering distribution measurements, it is necessary to use a large-scale device such as a positioner to measure exact measured position. To realize the system, we usually need enough manpower, large installation site and long observation time. In this paper, we aimed to realize a free scanning measurement system by the self-position estimation utilizing the "Kinect". In addition, we have adopted the FM-CW radar system and applied the synthetic aperture processing.

    Recently, researches on radio wave security sensors by using array antenna or MIMO have been attracting attention. Since signal subspace or MIMO channel matrix is used in these security sensors, these sensors have high detection performance and robustness as practical infrared sensors and video camera. Many systems and detection algorithms have proposed, and performance evaluation of computer simulation have been provided using simple 3D model. However, performance evaluation for varous intrusion has not provided yet. Inthis report, we evaluate statistical property of channel correlation for various intrusion model by computer simulation.

    This report described the accuracy of object location estimation for the application utilizing leaky coaxial cable. The facts that the accuracy varied according to the positional relation between object and LCX, and the signal frequency have been mentioned by using Cramer-Rao bounds for the maximum-likelihood estimation. Numerical simulation showed that the high accuracy region is related to observation frequency depending the radiation directivity of leaky coaxial cables.

    Coherent Change Detection (CCD) has been attracting attention in recent years. It is one of technique that detects changes between SAR image pair. CCD detects changes based on the coherence map between pair of complex data. We choose fully polarimetric data as the complex signal instead of single polarized data. CCD in the Ku-band is expected to be one of the key features as next generation airborne and satellite SAR application. Based on this situation, the CCD experiment has been carried out in anechoic chamber using three bandwidth (i.e. 0.5, 1.5, 2.0GHz). We show the changes of coherence image according to the bandwidth. As a result, the possibility of CCD even in the bandwidth of 0.5GHz is confirmed.

    In this report, we propose the scheme for measuring objects using surface and radiation mode of leaky cables. In those modes, response characteristics of the object are different. In radiation mode, it allows to measure the distant objects from the leaky cable. In surface mode, only the objects located adjacent to the cable can be measured. This report shows the response characteristics with those modes from experiments.

    Recently, superrcsolution techniques have become indispensable methods for Direction-of-Arrival estimation with an antenna array. Array elements often have gain and phase errors, in addition to that, mutual coupling effects cannot be negligibly small in general. Performance of the superresolution array is degraded by them. To realize high-resolution DOA estimation, array calibration is necessary. In this paper, we propose an array calibration technique based on subspace concept with known sources. Results of numerical simulation by NEC2 and experiment in radio anechoic chamber are reported to show the validty of the method.

    In this paper, we propose a calibration method of the ESPAR antenna by calculating an "equivalent weight matrix" which is a matrix composed of several equivalent weight vectors forming directional radiation patterns. We also present an experiment result that achieves a sharper MUSIC spectrum of about 20 dB in comparison with the case of no calibration in an anechoic chamber. In addition, after theoretically considering some more appropriate directive patterns, a simulation result clarifies that the appropriate directive patterns make a shaper MUSIC spectrum of about 10 dB than conventional directive patterns.

    In major application of subsurface radar, such as survey of buried pipe, a detection of target image is prevented from layer. Therefore, signal processing techniques which improve target image are proposed. In this study, a polarimetric signal processing is applied for detection of buried pipe. Since a target depth is relatively near to antennas, the present radar system can not consider mono-static. Accordingly, we use a T-bar fed slot antenna for subsurface radar. Because this antenna is very small, the new radar system is regarded as mono-static. This paper shows polarimetric radar images, and a capability of polarimetric subsurface radar is discussed.

    A T-bar fed slot antenna provides clear subsurface image for Ground Penetrating Radar. Because a parallel plate structure which consists radiator and surface of the ground suppresses a surface clutter. Furthermore, a modification of the feed section improves impedance matching between the antenna and radar equipment. To replace the T-shape feed section (typical design) with taper-shape, input impedance of the antenna reduce from 150Ω to 50Ω. This paper shows a frequency characteristic of the antenna with taper-feed section. And, results of radar detection performance using the antenna are presented.

    Radar image analysis is very important for monitoring global environment accurately. As compared with simple region such as flat surface, the scattering characteristics in vegetation area is difficult to analyze. Therefore it is necessary to develop the observation radar system for investigating scattering characteristics on vegetation. In this paper, we have developed an FM-CW radar system applicable to Polarimetric SAR Interferometry, and show some experimental results of a basic target and a foliage plant in anechoic chamber.

    Interferometry is a sensing technique which utilizes phase-difference of received waves by two receiving antennas. Using the interferometric technique, we can measure surface height change precisely. For the case of FM-CW radar, however, FFT method does not yield good results because of interference of beat-spectrum components. In this paper, we propose two methods on Interferometric FM-CW radar using ESPRIT algorithm. Simulation results show that the precise estimation can be realizeD by the proposed methods. The proposed methods are effective for Interferometric FM-CW radar.

    The preprocessing scheme using wave polarization is one of the effective techniques for resolution enhancement of superresolution techniques. In this report, we consider the validity of polarization averaging(PA)preprocessing scheme applied with the modified spatial smoothing preprocessing(MSSP)in the 2-D MUSIC estimation. The PA scheme enhances the decorrelation efficiency, which is mandatory for powerful coherent signal detection. We consider the decorrelation performance of the scheme in the 2-D problem theoretically, and also provide the experimental results to show the validity of the scheme.

    Recently, estimation improvements utilizing the polarization information of the electromagnetic wave have been important mainly in the remote sensing and the propagation analysis. In the superresolution technique, several modifications using the polarization data have reported. In this paper, we propose a new modification concerning with the data-correlation matrix for the superresolution technique (MUSIC algorithm). 0ur method has two main advantages for the conventional modification; 1) utilizing polarization difference of incoming waves for the signal decorrelation, 2) increasing number of resolvable signals. Therefore, resolution improvements can be realized. These advantages are verified by the computer simulations.

    This paper discusses the decomposition and recognition of complex targets based on the Sinclair scattering matrix and the principle of radar polarimetry. A scattering matrix, in general, may be decomposed into three fundamental scattering matrices, corresponding to plate (sphere), diplane, and helix. This decomposition is effectively carried out in the circular polarization basis, although the actual scattering matrix data set is obtained in the conventional liner HV polarization basis. The present method yielded a satisfactory recognition result in a laboratory experiment using a full polarimetric synthetic aperture FM-CW radar system operative at the Ku-band.

    In this research, we try to develop useful techniques for precisely grasping damage situation in wide flood area, by making full use of quad-pol SAR data. Here, by considering the analysis results based on fundamental study on electromagnetic wave scattering from simplified target models, three applicable methods are proposed for 1) observing and grasping the situation around flood river area, 2) detecting appropriate land roads for emergency rescue case, and 3) grasping the seasonal change of rice paddy field that is often used as temporary rainwater storage tank to mitigate flood disaster damage. It is verified from the results of PolSAR image analysis for actual quad-pol SAR data that each proposed method is useful.

    Preservation of the healthy earth environment is vital for all human beings. For monitoring the earth environment, remote sensing by airborne radar or space borne radar play important role for the purpose. Fortunately, Advanced Land Observing Satellite named "Daichi" was successfully launched by JAXA on Jan.24,2006. This satellite is the first space borne polarimetric SAR in the world. It has been attracting attention among world research institutions because of its fully polarimetric data take function.
    The purpose of the project has been "how to use the polarimetric data" and "what kind of information can be obtained?" In this regard, we carried out the research on decomposition of scattering power acquired by polarimetric radar. The results are summarized as follows :
    1)Four independent information can be extracted from polarimetric data
    2)Based on the second order statistics, we can construct various matrices. However, the essential components can be regarded as four.
    3)The covariance matrix and the coherency matrix can be decomposed into 4 sub-matrices which represent physical scattering nature. These are surface scattering, double bounce scattering, volume scattering, and helix scattering. The 4 scattering powers can be generated from these matrices. This decomposition technique is natural extension of the 3-component decomposition method previously proposed by Durden and Freeman at JPL, USA. The decomposition algorithm developed during the project is simple and easy to implement. Therefore it is quite useful for classification and identification of targets.
    4)The four components represent physical scattering characteristics very well so that one can see the scattering phenomena just looking into the decomposed color-coded POLSAR image.
    5)The result has been confirmed by airborne Pi-SAR datasets in Niigata Area.
    In addition, the principle of radar polarimetry together with the decomposition scheme and the project results are described in detail in a report so that students and/or beginners can join this important field.

    The purpose of this research was a three-dimensional imaging of terrain using polarimetric and interferometric synthetic aperture radar data. This polarimetric interferometric data-take requires very precise measurement for airborne radar within several cm repeat pass flight. Since this condition was too difficult to achieve for actual airplane, we paid main attention to classification and decomposition of polarimetric SAR data. The final purpose of radar remote sensing would be to find the details of target based on the polarimetric information. Thus, the research results conducted during the period are :
    1.Establishment of the principle of radar polarimetry
    It is important to establish a unified theory for polarimetric radar sensing. The principle of radar polarimetry from basic to its applications has been described in the research report.
    2.Establishment of X-band polarimetric SAR system
    (1)Set-up of polarimetric interferometric SAR in anechoic chamber.
    (2)Validation of acquired data from polarimetric point of view.
    3.Development of target classification
    (1)Search for best descriptor of polarimetric information among the statistics of the second order of cross-correlations, eigenvalue, polarization basis transformation, etc.
    (2)Development of four-component scattering model for polarimetric SAR image decomposition.
    (3)Ground truth for the four-component decomposition using Pi-SAR data acquired with Pi-SAR over Niigata area.

    This research aims at three-dimensional imaging of land cover using polarimetric and interferometric information obtained by Polarimetric and Interferometric Synthetic Aperture Radar (Pol-InSAR). The coherence between the scattering matrix elements yields information necessary for extracting scattering centers of two different height. This bring us the tree height estimation which is useful for estimating tree biomass. Therefore, the role of Pol-InSAR data is mandatory for monitoring the earth environment as regards CO_2 reduction.
    In this research project, we first carried out re-theoretical establishment on radar-polarimetry. Based on the principles, we verified the formulations of coherency, decomposition, polarimetric entropy, and averaged angle alpha in terms of scattering matrix elements. Then the coherency formulation is newly developed using ESPRIT algorithm, which can yield highly accurate scattering centers. Using E-SAR data set provided by DLR, Germany, actual tree height estimation was carried out successfully by the ESPRIT algorithm. The calculated result shows the effectiveness of Pol-InSAR data and also that two-polarization data yields similar tree height estimation. The overall results conducted by this project reveal that repeat-pass polarimetric data-take will provide us with tree height estimation which is necessary for biomass estimation.

    The purpose of this research is to pursuit the possibility of AIRBORNE POLARIMATRIC SYNTHETIC APERTURE RADAR for classifying and identifying land cover with polarimatric function. Fully polarimatric scattering matrix in the L-band is obtained by Pi-SAR (Polarimatric and Interferometric SAR), developed by CRL/NASDA. During the period of 1999-2001, Pi-SAR flew over Niigata Area several times. Fortunately, AIR SAR developed by NASA-JPL also flew over the same area in 2000, which eventually happened due to their Pacific Rim Campaign. Under these circumstances, we carried out our basic research on principle of radar polarimetry, SAR image classification, as well as laboratory measurement with validation, mainly focused on the following topics :
    1. Establishment of radar polarimetry principle and classification scheme based on the theory
    2. Polarimetric calibration of acquired data
    3. Validation of developed scheme in the laboratory experiment
    4. Derivation of efficient polarimatric index for classifying mart made targets ; against natural targets
    5. Development of classification software
    6. Validation of SAR data with ground truth measurement
    The above topics were successfully carried out in the period and several results were presented in international symposia and workshops. Most of them were successful, however, some still need to be resolved. The main difficulty was the information obtained by radar is radar scene specific, which requires specific information on the scene for accurate classification and identification. The overall classification accuracy with polarimetric information exceeded more than 80 % compared to 60 % for single polarization channel. This shows the advantage of polarization information for remote sensing technology.

    The purpose of the research project is to develope a new surveillance radar sytem to monitor disastered area using a polarimetric radar. The basic idea is as follows ; the polarization state of scattered wave from normal urban area will be different from that of area in case of disaster auch as earth quake because there will be building collapse. The difference in polarization state will serve as monitoring index to check the extent of disaster. In order to clarify and validiate the proposed method, we tried to use the full vector nature of electromagnetic information. The principle of radar polarimetry based on Sinclair scattering matrix brings us to classify targets by the following items :
    Characteristic polarization state
    Polarimetric enhancement
    Decomposition of scattering matrix into three basic types, sphere, diplane, helix.
    Polarimetric anisotropy coefficient
    Polarimetric entropy
    At first, we made miniture of buildings in an echoic chamber in Niigata University and used a full polarimetric FM-CW radar system in the X-band to acquire scattering matrix. After the polarimetric calibration of the radar system, it worked as an accurate polarimetric radar.
    Then, the radar system was used as a new surveillance radar sytem to monitor collapsed buildings in a laboratory measurement. The decomposition of scattering matrix into 3 basic components provided quite satisfactory results, and it was verified the single bounce component increases as collapse increases. The index of polarimetric entropy also supported the similar results. It is confirmed that the radar is effective for monitoring, provided that polarimetric radar is used in a proper condition including precise repeat pass.

    The purpose of the research project is to classify radar targets using full vector nature of electromagnetic information. The principle of radar polarimetry based on Sinclair scattering matrix enables us to classify targets by the following items :
    Characteristic polarization state
    Polarimetric enhancement
    Decomposition of scattering matrix into three basic types, sphere, diplane, helix.
    Polarimetric anisotropy coefficient
    Polarimetric entropy
    Using the above items, we tried to retrieve information on target.
    At first, we have designed and developed a full polarimetric FM-CW radar system operative in real-time mode in the X-band, which acquires 44 scattering matrices per second. A corrugated plate waveguides is also proposed as a polarimetric calibrator. The calibrator has a straight line polarization characteristic and operates in ultra wideband width. After the polarimetric calibration of the radar system, it yielded accurate scattering matrices.
    Then, the radar system was applied to classification of targets in a laboratory measurement. The decomposition of scattering matrix into 3 basic components provided quite satisfactory results, and it verified the importance of polarimetric information in radar remote sensing. The system has been also applied to the detection of objects in the underground. Using polarization anisotropy coefficient together with characteristic polarization states, the radar system yielded a fine classification results of buried target.
    For Synthetic Aperture Radar (SAR) image analysis, acquired with NASA-JPL AIRSAR, Shuttle Imaging Radar-C/X-SAR, and CRL/NASDA AIRSAR, we introduced an additional polarimetric information, i.e., polarimetric entropy. The combination of entropy with scattering matrix element, wavelet transform, based on the maximum likelihood method provided high-level classification performance.

    This research aimed at developing a full polarmetric and 2-dimensional synthetic aperture FM-CW imaging radar. The main purpose of this research was to introduce the principle of radar polarimetry into a wide-band FM-CW radar imaging. The radar polarimetry is a full utilization of the vector nature of the electromagnetic waves in radar remote sensing. The radar polarimetry has been well established for the monochromatic wave case, however, there still remains a question how to incorporate it into a wide band radar signal for the case of FM-CW radar. We pointed out in this research that the beat spectrum obtained in the FM-CW radar system could be replaced as a scattering matrix element which plays an important role in radar polarimetry principle. Since the beat spectrum after synthetic aperture signal processing has a complex amplitude (magnitude and phase) bearing polarimetric target information, it represents scattering characteristics of a target depending upon polarization. The value is evaluated at the center frequency of a swept frequency measurement. The authors investigated the transformation of scattering matrix in arbitrary polarization basis, which resulted in the derivation of the characteristic polarization states specific to a target, and polarimetric enhanced image against clutter. Using linear polarization basis configuration radar placed in a laboratory, several targets such as plate, dihedral corner reflector and wire, air-plane model were imaged to retrieve information from the scattering matrices. It was confirmed that the FM-CW radar acts as a novel, full polarimetric, high resolution, and revolutionary imaging radar system.

    この研究は、長さ1m程度の土壌に埋もれた物体を検出できる偏波FM-CWレーダ装置を開発し、遺跡探査用の道具に資することを目標としている.昨年度までの研究によりレーダの原形が作成できたので,今年度はそのレーダを使い,大学の構内や実際の遺跡現場で埋没物体の実測を行った.今までの理論結果から,地上に設定するアンテナの最適な高さがあることが実証されているので我々のシステムでは約30cmにホーンアンテナを設定し,探査を繰り返した.その結果,大学の構内の砂地で120cmの深さに埋めた幅30cmの金属板を検出することに成功した.また,検出結果を見やすくするために,レーダで得られるビ-ト信号の微分をとり,その結果を合成開口処理する方法で,深い位置にある物体を強調して表示できるようにした.この手法は,従来問題であった地表面の不要反射を大幅に減少させる効果があると共に埋没物体の検出を容易にする.この成果の意義は非常に大きい.一方,実際の遺跡現場で2回の実験を行った.場所は新潟県小千谷市真人原遺跡(1995.8.19)と新潟県黒崎町の緒立遺跡(1995.9.21)である.真人原遺跡では深さ30cm程度に作物の根による擾乱が検出できた.また,緒立遺跡では比較的電波の透過しやすい土壌であったため,地下70cm位に古墳を構成している石らしきレーダ画像が得られた.この結果は重点領域「遺跡探査」第3回公開シンポジュームにて報告した.今後,偏波と微分信号処理の理論的な検討を加え,さらに有効な埋没物検出レーダシステムに改良し,現場実験を行う予定である。

    この研究は、1m程度の土壌に埋もれた物体を検出できる偏波FM-CWレーダ装置を開発し、遺跡探査用の道具に資することを目標とした.昨年度までの研究により地中レーダとして適当と思われる周波数250-1000MHzを選定し,レーダの原形が作成できたので,今年度はそのレーダを使い,大学の構内や実際の遺跡現場で埋没物体の実測を行った.昨年度の理論結果から,地上に設定するアンテナの最適な高さがあることが実証されているので我々のシステムでは約30cmにホーンアンテナを設定し,探査を繰り返した.その結果,大学の構内の砂地で120cmの深さに埋めた幅30cmの金属板を検出することに成功した.また,従来より理論検討している偏波を使った検出実験を進め,散乱行列に基づく偏波データが地表面の不要反射を大幅に減少させると共に埋没物体の検出を容易にすることを確認した.この成果は偏波の重要性を確認すると共に理論的成果が実証されたことにつながり,その意義は非常に大きい.一方,実際の遺跡現場で2回の実験を行った.場所は新潟県村上市磐船浦田山古墳群(1994.721)と群馬県北群馬郡子持村(1994.12.8-9)である.村上市では深さ20cm程度に礫が数多く埋もれていたが,海岸に面しており,塩分が多く含まれている土壌であったために電波の減衰が大きく,あまりはっきりしたレーダ画像は得られなかった.子持村では比較的電波の透過しやすい土壌であったため,地下1m位に古墳の頂上らしきレーダ画像が得られた.この結果は重点領域「遺跡探査」第3回公開シンポジュームにて報告した.今後,偏波の理論的な検討を加え,さらに有効な埋没物検出レーダシステムに改良し,現場実験を行う予定である。

  • Research on Synthetic Aperture FM-CW Imaging Radar Utilizing Polarimetry

    This research aimed at developing a 2-dimensional synthetic aperture FM-CW radar utilizing the full vector nature of the electromagnetic waves, i.e., radar polarimetry. The main purpose of this research was to introduce the principle of radar polarimetry into wide-band FM-CW radar imaging. The radar polarimetry has been well established for the monochromatic wave, however, there still remains a question how to incorporate it into a wide hand radar signal for which FM-CW radar resides. The authors pointed out in this research that the beat spectrum obtained in the FM-CW radar system could be replaced as a scattering matrix element which plays an important role in radar polarimetry. Since the beat spectrum after synthetic aperture signal processing has a complex amplitude (magnitude and phase) bearing polarimetric target information, it represents scatttering characteristics of a target depending upon polarization. The authos investigated the characteristic polarization states which are specific to a target in detail as well as the 2-dimensional FM-CW radar imaging principle. Using two linear orthogonally placed targets in a laboratory measurement, it is confirmed that the FM-CW radar acts as a full polarimtric imaging radar system.
