Abstract

This paper studys several kinds of MUSIC algorithms in DOA estimation, expounds the principle of Root-MUSIC algorithm, beamforming MUSIC algorithm, spatial smoothing MUSIC algorithm, conductes simulation for uniform linear array with Matlab, get the characteristics of three kinds of algorithms, Root-MUSIC algorithm is suitable for high SNR, the performance of beamforming MUSIC depends on the selection of matrix, spatial smoothing MUSIC gets the DOA estimation of coherent signals with the cost of reducing the antenna aperture, provides a reference for practical use.
