摘　　要：性能测试和算法验证是雷达信号处理分系统评估过程中必不可少的环节,为了获得精确的评估结果,通常需要回波模拟来验证雷达信号处理算法的有效性和稳定性。传统雷达回波模拟器大都基于DSP+FPGA的架构,其成本较高且升级维护比较困难。本文通过对数字相控阵雷达建模,基于CPU+GPU平台设计了一种雷达回波模拟器,解决了传统模拟器难以升级维护的问题。在实验室内与雷达波控、信号处理、预处理、数据处理以及终端搭建起一套完整的仿真验证系统,经系统联调验证,该模拟器可以模拟雷达多种工作模式。Performance test and algorithm verification are indispensable for radar system evaluation.In order to obtain accurate evaluation results,radar echo simulator was used to test the availability and stability of signal processing algorithms.The traditional radar echo simulator was mostly based on DSP+FPGA architecture,which was expensive and difficult to upgrade and maintain.Through modeling digital phased array radar,a radar echo simulator was designed in this paper based on CPU+GPU platform,which solved the problem of upgrading and maintaining.In the laboratory,a complete simulation verification system was built with radar wave control,signal processing,preprocessing,data processing and terminal.After system joint adjustment verification,the simulator can simulate various working modes of radar.
