雷达回波模拟器的设计与实现

Design and Implementation of Radar Echo Simulator

雷达回波模拟器在雷达系统的性能测试中具有广泛的应用。介绍一种多功能小型化雷达回波信号模拟器的工作原理和实现结构。该设备可以模拟LFM信号、脉冲信号等多种信号波形,具有较宽的多普勒调制和时间延迟调节功能,能有效验证脉冲压缩与信号处理单元的工作性能,准确评估雷达系统的分辨力、威力范围等技战术指标。同时该设备也可作为一种简易实验平台为其他雷达系统提供信号源输入。

Radar echo simulator is used widely in radar performance measuring, This paper introduces the work principles, hardware circuit structure and application of a pint - sized multifunctional radar echo simulator, which can generate various waveforms needed. We can modulate the Doppler frequency and adjust the time delay of the waveform to validate the performance of radar system. The simulator can also be used as a signal generator to provide the input of the other radar system.
