Antenna Array Calibration Using Known Sources(2) : Consideration on reduction of number of Data Sets

HARA Rokuzou, ARAI Takahiro, YAMADA Hiroyoshi, YAMAGUCHI Yoshio

ITE Technical Report 25 ( 74 ) 61 - 67 2001.11

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.

On polarimetric scattering characteristic of building at miniature model experiment

TSURUMAKI Kouichi, YAMAGUCHI Yoshio, YAMADA Hiroyoshi

Technical report of IEICE. SANE AP2001-151 ( 11 ) 47 - 52 2001.11

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

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.
