摘要
提出了一种新型的水雷声引信。该引信使用的是水下声强矢量而不是以前通常使用的声压,并且采用双水听器信号的互谱方法测量水下声强矢量。这使得引信能够利用更多的舰船目标信息,其结果是该引信在目标的定位和识别方面具有显著的优势。
A new mine acoustic fuse is presented. The fuse makes use of an underwater sound intensity vector which can be measured by the cross-spectral density of two hydrophone signals rather than sound pressure which usually was used before, so that it can utilize more ship's information. As a result, it has the remarkable advantages in target location and identification.
