摘　　要：本文针对SAR系统的测试需求,设计了一套基于LabVIEW的SAR回波模拟源。该模拟器利用LabVIEW虚拟仪器技术实现人机交互,能够根据目标回波参数生成所需的SAR回波数据,并通过PXI总线控制信号发生器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系统测试需求,具有很高的工程应用价值。To meet the testing requirements of SAR system, this paper presents a SAR echo simulator based on LabVIEW. The simulator realizes the human-computer interaction function with a virtual instrument technology- LabVIEW,and provides the echo data according to the target echo parameters. Moreover, the simulator can generate two orthogonal waveforms though PXI bus. The compression results show that the echo signal quality of the simulator is good and the system can be realized in real time to fit the requirements of the SAR system testing.
