This paper studies several kinds of MUSIC algorithms for the arrival (DOA) estimation of signals,which is an important branch in array signal processing.The theories of classical MUSIC algorithm,Forward/Backward spatial smoothing MUSIC algorithm,and modified MUSIC algorithm are expounded.Simulation by Matlab shows that classical MUSIC algorithms are good in performance for estimating the doas of incoherent sources,but fails for coherent sources;the Forward/Backward spatial smoothing MUSIC algorithm decreases the source number,and increases the amount of calculation;modified MUSIC algorithm offer the best performance without affecting the estimation of relevant source or significant increase in the amount of calculation.These algorithms for the doas estimation have their own advantages and disadvantages.

Key words: MUSIC;spatial smoothing MUSIC;modified MUSIC;DOA
