Abstract This paper presents the performance analysis of the MUSIC algorithm in the presence of channel mismatching. Theoretical expression for the error of DOA estimating with MUSIC algorithm and Cramer-Rao bound are derived. It is compared with simulations performed for some representative cases. The results of theoretical expression and simulation show that existence of channel mismatching will increase the error of DOA estimating and degrade its performance.

Key words： Channel mismatching Estimation of Direction-of-Arrival（DOA） Adaptive array
