单只矢量水听器对多目标方位估计的仿真研究

A Vector Hydrophone Pairs of Multi-objective Simulation of DOA Estimation

文章结合了矢量水听器的自身特点,利用单只矢量水听器分别研究了声强法和ESPRIT算法对目标方位进行估计,在无需知道信号先验信息的条件下,可以实现对多个不相关信号的方位角估计。利用已知的条件进行模拟仿真,在不同的信噪比,样本长度的条件下来对比声强法与ESPRIT算法之间了优劣性。

In this paper,according to the characters of the vector hydrophone,DOA（direction of arrival） of target is estimated with single vector hydrophone by sound intensity and ESPRIT algorithm separately,which may carry out the estimation of azimuth angel and elevation angle of several uncorrelated signals.Simulation is carried on according to some fixed conditions using sound intensity and ESPRIT algorithm under different SNR and length of the sample,and the performances are compared with each other.
