摘要
矢量水听器利用MVDR波束形成器可以对目标信号进行波达方向估计,对三维矢量水听器和二维矢量水听器的MVDR波束形成器的性能进行分析研究。结果表明:三维矢量水听器的MVDR波束形成性能较好,而当干扰信号远小于环境噪声时,二维矢量水听器MVDR波束形成对在水平方向上的目标信号有很高的分辨率。
Vector hydrophone adopts MVDR Beam forming equipment to estimate the direction-of-arrival of target signal. Analyze the MVDR beam forming equipment performance of three-dimension vctor hydrophone and two-dimension vctor hydrophone. The results show that the MVDR performance of a three-dimensional vector hydrophone is better than a two-dimensional vector hydrophone. But a two-dimensional vector hydrophone has high resolving power at the signal impinges from horizontal arrival angles when the additive interference power is less than environmental noise power.
