【摘要】In order to distinguish the multi-source using a single acoustic vector hydrophone ,the prob-lem on blind estimate of underwater acoustic vector signal is studied .According to the characteristic of single acoustic vector hydrophone ,a new algorithm combining the blind source separation and the technique of single vector hydrophone array is proposed to estimate multi-source .With no priori infor-mation ,the array manifold is estimated , and the sources are separated . Finally , the azimuths of sources are estimated with the orthogonality of the components of particle velocity .The results of processing data testify the validity of the algorithm .%为实现单矢量水听器的多目标方位估计，研究了水声矢量信号的盲估计问题。根据单矢量水听器的阵列流型特点，结合盲源分离技术，提出了一种新的单矢量水听器多目标方位估计算法。在目标信号先验信息未知的情况下，该算法可分离出各目标信号及其阵列流型，然后利用单矢量水听器振速分量的正交性，估计出各目标信号的方位。实验验证了该算法的有效性。 【总页数】4页(775-778)
