Traditional algorithm of direction of arrival estimation in low SNR ratio conditions poor performance problems,an estimation algorithm for direction of arrival based on improved MUSIC algorithm is proposed in this paper.Firstly the shortcomings of multiple signal classification algorithm is analyzed,and temporal smoothing technique is used to construct the correlation matrix,and then correlation matrix is used to construct spectral function and estimate direction of arrival,finally the performance of the algorithm is tested by the simulation experiment.The results show that,the proposed algorithm can rapidly and accurately estimate the direction of arrival for multiple signals,direction of arrival estimation error is reduced,and the performance is superior to the other modified multiple signal classification algorithm.
