摘　　要：文中依据鱼雷自导系统性能测试仪的主要功能及其信号处理的特点,选择ADSP21160作为其信号处理器,并按照模块化结构设计的思想,将测试仪设计成为一个多模块、多处理器系统。该系统采用全数字方式产生回波信号、噪声及混响,可以提供模拟输出信号、数字输出信号;可在主控机的控制下工作、也可自主工作;可以模拟单个目标,也可模拟多个目标;可以模拟静止目标,也可按目标运动轨迹模拟运动目标;可以模拟窄带回波,也可模拟宽带回波;可以模拟单亮点,也可模拟多亮点。Based on the main function and signal processing characteristic of performance rester of torpedo homing sys- tem,the main DSP used in this paper is ADSP21160.According to design thought of modularized structure,the per- formance tester is designed as a multi-modular,and multi-processor system.This system generates echo signal,noise and reverberation by whole digital mode.The system is able to provide analog output signals and digital output signals. It operates controlled by main console or itself.It can simulate single-target,single-spotlight or multi-target multi-spot- light and quiescent target or moving target.The performance tester may simulate narrowband or broadband echo signal.
