基于方位走向法和互谱法的水中目标识别

Underwater Target Identification Based on the Methods of Bearing and Cross-spectrum

阐述基于目标方位走向法的目标识别理论,提出利用体目标回波的空间方位分布信息识别水下目标尺度信息的方法。最后通过计算机仿真给出在不同攻击条件下,鱼雷对潜艇目标进行尺度识别的估计量、估计方差并进行相应的分析。

A method of underwater target dimension identification was proposed by special bearing distribution data of body target echo based on identification theory of a target bearing method. The estimating value and variance of identified submarine dimension with torpedo were given and analyzed by computer simulation at different attack conditions.
