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.
