摘　　要：利用电磁场分析软件FEKO,研究了抛物面天线在破片穿孔时天线方向图的变化规律。通过对物理光学法(PO)和物理绕射理论(PTD)的混合使用,对战损后抛物面天线的电气性能进行了建模与分析,以比较反射面损坏前后对天线方向图的影响。着重研究了天线反射面毁伤后,毁伤孔数、孔径及其位置变化对方向图的影响。The radiation pattern of paraboloid antenna after damaged is studied by using the software-FEKO analysis specially served for electromagnetism field.The model of paraboloid after damaged is modeled and analyzed by using the method of PO and PTD.Comparison of radiation capability between good reflector and damaged reflector is made.Especially the radiation pattern of paraboloid is studied when the size,number and position of damaged hole are changed.

关 键 词：反射面 破孔 方向图
