Abstract：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.

新一代天氣雷達(dá)通過(guò)電磁波對(duì)云雨等目標(biāo)物的探測(cè)，已在臺(tái)風(fēng)、暴雨和強(qiáng)對(duì)流等災(zāi)害性天氣的監(jiān)測(cè)、預(yù)警、預(yù)報(bào)和氣象災(zāi)害防御過(guò)程中發(fā)揮了不可替代的作用［1-3］，隨著社會(huì)經(jīng)濟(jì)的發(fā)展，電子設(shè)備工作領(lǐng)域和工作方式的增多，使得無(wú)線射頻信號(hào)在近十年內(nèi)對(duì)氣象雷達(dá)的影響越發(fā)嚴(yán)重，已引起氣象學(xué)界的特別關(guān)注。（剩余5204字）
