摘　　要：提出了一种基于Agilent N8241A任意波形发生器和E8267D矢量信号发生器的宽带LFMCW雷达回波信号模拟器设计方案。该设计方案采用计算机产生LFMCW雷达信号波形数据,由N8241A通过DAC将其转化为宽带IQ基带信号,再经过E8267D进行IQ调制最终转换为微波射频信号输出,供实验室条件下宽带LFMCW雷达测试使用。实验结果表明,该模拟器具有良好的通用性和精确度,且结构简单。An wideband LFMCW radar echo signal design sheme based on Agilent N8241 A arbitary waveform geneator and E8267 D vector signal generator is presented. This scheme uses computer to generate LFMCW radar signal waveform data,which is changed to wideband IQ baseband signal by DAC with N8241 A,then performed IQ modulation by E8267 D to convert into microwave RF signal finally to deliver for testing wideband LFMCW radar in lab condition. The experimental result indicates that the simulator provides perfect generality and precision not only,but also the structure is simple.
