摘　　要：某机场在一次DVOR 4000型设备的定期飞行校验中发现该信标在磁方位角150°~350°的区域内方位误差超限,导致该台站限用。本文通过对2019年和2021年2次飞行校验的图纸数据进行对比,并结合多普勒全向信标(DVOR)的信号模型进行了理论分析、设备天线测试、外场干扰测试,最终得出导致此次方位误差超限的原因为电磁信号干扰。During a regular flight inspection of DVOR 4000 equipment in an airport,it was found that in the magnetic azimuth of 150°~350°,the azimuth error was out of limit,which led to the limited use of the station.By comparing the drawing data of two flight inspections in 2019 and 2021,and in combination with the signal model of DVOR,this paper carries out theoretical analysis,equipment antenna test and field interference test,and finds out that the cause of the out-of-limit azimuth error is electromagnetic signal interference.
