摘　　要：利用FEKO电磁场分析软件，研究了双模圆锥喇叭在破孔时方向图的变化规律。通过运用矩量法对战损后馈源辐射特性进行了建模与分析，以比较馈源破孔后对其方向图的影响。着重研究了馈源单孔损伤后，破孔孔径、水平位置和方位位置变化对方向图的影响。The radiation pattern of dual-mode conical horn after damaged is studied by using the FEKO electromagnetism field analysis software. The model of dual-mode conical horn after damaged is established and analyzed by using the method of MOM. Comparison of radiation capability between good horn and damaged horn is made. The radiation pattern of horn is studied as an emphasis when the size, horizonal and direction position of damaged hole are changed.
