摘　　要：结合新一代天气雷达工作原理和信号传输流程,利用台站现有方式对雷达自身和外界干扰源进行初步判断,明确了2019年至2021年间承德天气雷达站出现的异常回波均为附近工地塔吊所使用的无线网桥监控信号干扰所导致,通过对处置过程的总结分析,可为从事天气雷达保障工作的同行提供参考借鉴。Combined with the working principle and signal transmission process of CINRAD/CB,the existing mode of the station is used to preliminarily judge the radar itself and external interference sources.It is clear that the abnormal echo of Chengde weather radar station from 2019 to 2021 is caused by the interference of the wireless bridge monitoring signal used by the tower crane at the nearby construction site.Through the analysis of the disposal process,It can provide reference for colleagues engaged in radar technical support.
