摘　　要：本文采用六盘水市新一代多普勒天气雷达受电磁波干扰数据资料,从雷达电磁波干扰监测测试点的方位、距离、强度等找出干扰源并分析其原因。论述电磁波干扰源的判定过程,采用信号源进行逐级测试排查,确定不是天气雷达自身干扰后,判定为外界电磁波干扰,找出干扰源并关闭进行政处理过程。最后结合C1NRAD/CA天气雷达的抗干扰能力,对同频干扰现象及其解决措施从理论上进行了探讨,并为其他同行提供有益的参考。In this paper, the electromagnetic interference data of the new generation Doppler weather radar in Liupanshui City are used to find out the interference sources and analyze the reasons from the azimuth, distance and intensity of the radar electromagnetic interference monitoring test point. This paper discusses the determination process of electromagnetic wave interference source, using the signal source to test and check step by step, to determine that it is not the weather radar itself interference, determine the external electromagnetic wave interference, find out the interference source and close the administrative process. Finally, combined with the anti-jamming ability of CINRAD/CA weather radar, the phenomenon of the same frequency interference and its solving measures are discussed theoretically, and provide a useful reference for other counterparts.
