下视条件下水声目标模拟器设计

针对在下视条件下水下目标的特点,开发了一种用于调试和试验目标模拟器系统。该系统以TMS320数字处理芯片和MSP430单片机为核心,突破了信号检测和抗互导等关键技术,实现了对目标回波信号的实时模拟。大大方便了深弹自导系统的调试和试验,该系统已经成功运用于水池、湖上和海上试验。

Design of Underwater Acoustic Target Simulator Under Downward-looking Condition

According to the characteristic in underwater acoustic target ,a design of real underwater targetsimulator used for de-bugging and test is introduced. It is composed of TMS320 and MSP430,key technologies breakthroughs are pulse signal detec-tion and reverberation mutual conductance,it successfully implement the simulation of echo signal of target.This system have been applied in the anechoic tank experiment and lake and sea experiment,greatly faciliating the development of underwater self-guide systern.
