| 摘 要： | 为解决拖曳线列阵声呐的左右舷模糊问题,提出了一种新的二元水听器组左右舷分辨方法.该方法以移相处理为基础,将单个二元水听器看作一个小基阵.移相处理的目的是使从镜像源方向来的信号经处理后最小,进而使单个二元水听器具有心形指向性,从而保证二元水听器组能够分辨目标所处的左右舷.经过理论分析和湖试数据验证,证明了这种方法能有效解决大横截尺寸二元水听器组和小横截尺寸二元水听器组的左右舷模糊问题,适用范围广,算法简单,计算量小.

| Abstract: | In order to solve the port/starboard ambiguity for the towed linear array sonar, a new port/starboard discrimination method of towed linear array of hydrophone two-tuples is presented in this paper.This method is based on the phase shift processing,in which the single hydrophone two-tuples is regarded as a little array,and the aim of phase shift processing is to make that the signal from image source minimized after signal processing,thus make that the single hydrophone two-tuples have cardioid directivity,... |
