摘要
雷达目标模拟器在汽车毫米波雷达系统的性能测试中具有广泛的应用,其性能指标直接关系到整个雷达系统的最终性能参数。文章提出一种适合多种波形汽车毫米波雷达的目标模拟设备,该模拟器采用数字射频存储(DRFM)技术和直接数字频率合成(DDS)技术,提高了系统精度,扩展了小距离覆盖范围。使用结果表明,该模拟器满足多种雷达波形体制的测试需求。
Radar target simulator is widely used in radar performance measuring, which performance is directly related to the ultimate performance parameters of the radar system. This paper presents a target simulation device suitable for multi -wave vehicle millimeter wave radar. The simulator adopts DRFM technology and DDS technology to improve the precision of the system and extend the coverage of small distance. The results show that the simulator satisfies the testing requirements of mul- tiple radar waveform systems.
