摘　　要：针对水下声自导系统调试及实验参数设定的需求,开发了一种实时水下双目标回波模拟器系统,该系统模拟目标的声学反射特性,接收主动探测信号并根据实验需求模拟目标的反射回波信号特征,可在有相邻干扰的情况下应答两个主动探测信号。该系统模拟目标信息完整、准确、功能可扩展,用户可以通过上位机实时监测模拟器的工作状态,实现对模拟器目标参数的修改。经过消声水池及湖上实验,该目标模拟器已经成功应用于水下自导系统,性能满足实际需求。According to the actual needs of underwater acoustic homing system in system debugging and setting up experiment parameters, a new design of real water double targets simulator is introduced. The system simulates the acoustic reflection characteristics of the target, receives active detection signal and emits signals of reflection echo characteristics. The target simulator can response up to two active detection signals in the condition of interference. This system is complete, accurate and can be extended. The user can monitor the working state of simulator and change the parameters of simulator. As a result of an echoic tank experiment and lake experiment, the system has been successfully applied to the underwater homing system.
