摘要
本文提出了一种利用大动态范围脉冲幅度自动增益控制技术和数字波形存储技术，实现水下目标信号存储和目标回波波形模拟的方法。利用该方法设计的声纳目标应答机，经多次湖试和海试验证，技术方案可行，并取得了满意的波形模拟效果。文中主要介绍了目标信号存储与回波波形模拟的基本原理、系统时序控制关系、海试结果等。
A method for acoustic signal storage and simulation of underwater target is presented in this paper. The techniques of large dynamic pulse gain control and digital waveform storage are applied. The basic principles for acoustic signal storage and target echo simulation, the control logic of system time relationship and performance analyses are introduced in this paper. its feasibility and satisfied waveform simulations have been verified through sea trail and lake trail.
