Abstract

In this paper, a new angular super-resolution technique called Phase Weighting Super-resolution Method (PWSM) based on Hadamard matrix is proposed, which is used in conventional phased array radar for improving angle resolution. The phase shifting necessary to steer the main beam of the aperture coupled micro-strip antenna is achieved by 0-π MEMS phase shifters, which are integrated in a hybrid fashion between the antenna and feed network. The results of the measured pattern are consistent with the theoretical calculation results.
