摘　　要：DRS05测速雷达是一种多普勒雷达,广泛应用于轨道交通。本文介绍了一种基于数字射频存储(Digital Radio Frequency Memory,简称DRFM)的DRS05测速雷达测试方法,可有效地对DRS05测速雷达进行健康监测和故障排查。本文介绍的基于DRFM的DRS05测速雷达测试方法,可以按照预设的列车运动状态对DRS05测速雷达进行目标回波模拟,监视雷达发射信号频谱,检测雷达健康状况,实现雷达故障模块的精确定位。DRS05 velocity radar is a kind of Doppler radar, which is widely used in rail transit. This paper introduces a test method of DRS05 velocity radar based on Digital Radio Frequency Memory(DRFM),which can effectively monitor the health and troubleshooting of DRS05 velocity radar. It can simulate the target echo of DRS05 velocity radar according to the preset train speed, monitor the radar transmission signal spectrum, detect the radar health status, and realize the accurate positioning of radar fault module.
