| 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 recog- nition,respectively.Based on the average time-delayed correla- tion 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.Experi- mental results show that this method is superior to the multiple signal classification (MUSIC) method for realizing the same res- olution at the same situation. |
