摘　　要：阵元接收信号是主动声纳信号处理的基础,针对主动声纳实时仿真系统的需求,论文依次对海洋混响、海洋环境噪声进行了建模仿真,并提出一种优化目标亮点回波建模的方法,该方法不仅可以反映运动目标的多普勒效应,还能有效模拟水下目标在姿态与态势发生变化时目标回波的时延变化和强度起伏特性。The echo signal is the basis of array active sonar signal processing.In order to meet the requirements of real-time simulation system of active sonar,reverberation and ambient noise are analyzed through modeling simulation,and a method of opti⁃mizing target highlight echo modeling is proposed.This method can not only reflect the Doppler effect of moving target,but also can simulate the characteristics of delay and intensity fluctuation of target echo effectively.
