摘　　要：针对SAR系统的测试要求,设计了一套基于DSP处理器TS101的SAR回波模拟器。该模拟器采用标准的CPCI 6U板。利用CPCI总线技术实现人机交互,能够根据目标回波参数生成所需的SAR回波数据,并通过DSP的链路口输出两路正交回波信号。测试结果表明,该模拟器生成的回波信号质量高,实时性强,能够满足SAR系统测试的需求,具有很高的工程应用价值。To meet the testing requirements of SAR system,a SAR echo signal simulator based on TS101 was designed.The standard compact PCI 6U board is adopted in the simulator.The human-computer interaction is realized with compact PCI bus tecnology.The SAR echo data can be generated according to the target echo parameters.Moreover,the simulator can output two orthogonal echo signals through link ports of TS101.The test results show that the quality of the echo signal generated by the simulator is good and can meet the requirements of the SAR system testing.
