A Kind of Method for Direction of Arrival Estimation Based on Blind Source Separation
-
摘要: 方位估计和信号恢复分别是水下目标跟踪和识别的前提. 基于平均时间延迟相关矩阵提出了一种复数域盲源分离方法, 在此基础上实现了DOA估计和信号恢复. 实验结果表明, 该方法在同等条件下完成同样的方位分辨要优于多重信号分类(Multiple signal classification, MUSIC)方法.

Abstract: Direction of arrival estimation and signal recovery are the bases of the underwater target tracking and target recognition, respectively. Based on the average time-delayed correlation matrices, a new kind of complex blind source separation is proposed. Then the DOA estimation and the corresponding signals of targets are calculated based on this method. Experimental results show that this method is superior to the multiple signal classification (MUSIC) method for realizing the same resolution at the same situation.
