The performance evaluation of estimation of DOA via MUSIC algorithm with mutual coupling between transmission and reception antenna elements

摘要

In this report, a performance of estimating the Direction-Of-Arrival (DOA) using MUSIC algorithm is evaluated when transmission and reception are performed simultaneously Since the transmission and reception antenna elements have mutual coupling, the transmitted wave leaks to reception antenna elements. The steering vector of this transmitted wave is modeled under the existence of this mutual coupling for estimating the DOA of the reflected wave from the target.
