This paper analyzes the statistical performance of the high resolution parameter estimation algorithm MUSIC in the case of inconsistent channel frequency response (channel mismatch), and deduces the influence of channel mismatch on the spatial spectrum and the relationship between mismatch variance and resolution. The theory shows that the channel mismatch has a great influence on the performance of the algorithm, and the computer simulation results prove the validity of the theory.
