基于自适应Notch滤波器的矢量阵多目标分辨研究

摘要

A novel method of acoustic vector sensor beam forming with adaptive Notch filters is proposed to solve the problem of multi-sources distinguishing on small platforms. Its theoretical basis and beam pattern are analyzed in detail. The multi-sources detection and distinguishing are realized by using frequency selection in the adaptive Notch filter and the spatial directivity of the vector array. Theoretical analysis and simulation show that the proposed method is superior in performance to the conventional vector array beam forming.%为解决水下小平台上的多目标分辨问题,提出了一种基于自适应Notch滤波器的矢量阵波束形成方法.给出了矢量阵自适应Notch滤波器波束形成原理与波束图分析,利用自适应Notch滤波器的频率选择与矢量阵空间指向性,实现了多个目标的检测与分辨.理论分析与计算机仿真表明,该方法的多目标分辨性能优于矢量阵常规波束形成方法.
