Abstract (in Japanese) (See Japanese page) 
(in English) Recently, spatial signal processing techniques with array antenna have been realized in various applications. In these applications, array calibration is indispensable to achieve best performance. The authors proposed a new array calibration technique based on the modification of equivalent circuit equations of the array having single-mode elements, such as half-wavelength dipoles, and showed that the proposed technique was effective for high-resolution DOA estimation. That was the application of array in receiving mode. In this report, we analyze array calibration problem in transmission by the proposed definition of equations, and show that the calibration matrix for an arrays in transmission is different from that for the array in reception when the array is not optimally matched.
