| 摘 要： | 矢量水听器通常由三个空间轴向垂直的振速水听器和一个声压水听器构成，可同时测量声信号的振速和声压．为了了解复杂分界面上矢量水听器阵列的定向性能，根据分界面上平面波的反射模型，提出了改进的Bartlett和Capon空间谱，建立了统一框架，并且在绝对硬边界典型界面下，分析了基于矢量水听器阵列的定向性能．给出了具体算例．

| Abstract: | A vector hydrophone is composed of three spatially co-located but orthogonal oriented velocity hydrophone plus another co-located pressure hydrophone. To understand the performance of DOA estimation using vector hydrophone array in a reflecting boundary, based on the reflecting model of plane acoustic wave, the improved Bartlett and Capon spatial spectrum are presented, and then the general frame is set up. The ability of DOA estimation is also analyzed in the reflecting boundaries such as rigid boundary,at last three examples are given. |
