| 摘 要： | 由于单个声压水听器无指向性,不能用来估计目标的方位,因此提出了一种基于单个矢量水听器的高分辨MUSIC算法。该矢量水听器由3个空间轴向垂直的振速水听器和1个声压水听器构成,充分利用矢量水听器的阵列流形特性,按照阵列信号处理的原理对其输出的标量场和矢量场信息进行联合处理,构造了单矢量水听器MUSIC算法。仿真结果显示,将MUSIC算法应用于单矢量水听器可以得到比Capon算法更尖锐的指向性波束,更低的旁瓣,大大提高了对目标的分辨能力,在高信噪比条件下能实现对目标高分辨的方位估计。

| Abstract: | For the reason that the single omni-directional pressure sensor can't estimate the target azimuth,the high resolution MUSIC algorithm for DOA estimation using a single vector hydrophone is presented.The vector hydrophone is composed of three spatially co-located but orthogonally oriented velocity hydrophones plus another co-located pressure hydrophone.Based on array signal processing theory,the pressure and particle velocity are processed jointly to construct a direction of arrival(DOA) estimation algorithm... |
