摘　　要：介绍了被动测距声呐定位的基本原理,运用时-空转换的哲学思想,给出了m个水听器组成的舷侧阵目标定位线性阵变最小二乘法,进而给出了目标速度与航向的估计。为纯方位远距离、大误差、低分辨率目标运动分析,给出了理论数学模型。The locating principle of passive ranging sonar is introduced. Based on philosophy ideology of time- space conversion, linear array variable least square methods is built for flank array sonar locating, which is composed of m hydrophone. Furthermore,target＇s speed and course is estimated. Theoretical models are presented for analyzing the movement of the targets at far distance, with large error and low resolution.
