Array signal processing is an important branch of the modern signal processing, and the source orientation is an important application of array signal processing. The MUSIC algorithm, can super distinguish the direction of arrival (DOA).Through the simulation, the paper Comprehensively analyzed the classical MUSIC algorithm, Roots MUSIC algorithm, the fourth-order cumulant MUSIC DOA estimation algorithm, it analyzed the performance of three algorithms in the same signal noise ratio and in different signal-noise ratio, it is indicated that the signal-noise ratio is an important influence factor of the resolution of the MUSIC algorithm.
