摘　　要：为了配合某型C波段宽带雷达系统进行设备调试和功能检查,模拟器采用软硬件结合的方法。当雷达发射窄带信号时,目标回波通过对雷达发射信号进行延迟、频移等实现;当雷达发射宽带信号时,采用波形预先存储的方式进行回波的产生。模拟器通过操控计算机输入不同的雷达参数、目标特性数据,能模拟雷达所需的射频目标回波信号,以达到不同的测试要求,具有使用灵活、低成本、扩展性强的特点。To cooperate the debugging and testing of a C-band wideband radar,a simulator is implemented by adopting method of combining software and hardware.The simulator produces the echo signal by delaying the radar＇s signal when the radar transmits narrowband signal,however,it produces the echo signal depending on the radar＇s wave data which are stored in the memory beforehand when the radar transmits wideband signal.By inputting radar＇s different parameters and targets＇ characteristic through it can be used to adjust and test radar signal receiver and reach different test requirement.The instrument features convenient and low cost and can change its function with various requirements.
