| 摘 要： | 现代声纳系统普遍采用水听器基阵和一定的信号处理来提高对目标的检测和定位能力，而基阵的波束形成则在其中起着核心作用。文中研究了窄带波束域高分辨方位估计技术，分析了波束域MUSIC方位估计的构造过程和具体实现方法。仿真计算表明，基于波束域MUSIC的方位估计算法是一种分辨空间小角域内多个目标的有效方法。

| Abstract: | Modern sonar systems generally use hydrophone arrays and advanced signal processing techniques to improve their detection and localization abilities, and beam forming plays an important role. Narrowhand beam space high resolution bearing estimation techniques are studied in this paper. The construction procedure and performance of beam space MUSIC algorithm are analyzed for the weak correlated signals. Computer simulation results show that the beam space MUSIC algorithm has its super performance. |
