摘　　要：针对多站制连续波(CW)雷达工作特点,设计了一种CW雷达目标动态模拟器,满足多站连续波测量系统动态模拟联试的需求。采用高性能CPCI工控机作为模拟器硬件平台,信号处理单元以CPCI板卡为载体,模拟控制信息依据弹道数据生成。模拟器通过控制测距信号的时间延迟,实现目标距离变化的模拟;通过载波频移控制,实现目标速度的模拟;通过数控衰减器控制模拟信号的幅度,实现目标信号强弱的模拟。通过多站制测量系统动态模拟联试,验证了模拟器的有效性和距离与速度的相关性。According to the features of multi-station continuous wave（CW） radar, a dynamic target simulator for CW radar is designed. The simulator meets the needs of dynamic simulative test for the multi-station CW measurement system. The high-powered CPCI computer is the hardware platform of simulator. The signal processing unit is built by CPCI board. The simulation control information is transformed by trajectory data. The change of target distance is simulated by controlling the delay of ranging signal. The change of target velocity is simulated by shifting the frequency of carrier wave. The signal intensity is simulated by numerical control attenuator. The result of multi-station measurement system dynamic simulative test has proved its validity and the correlation between distance and velocity.
