赋形反射面天线毁伤效应研究

A Study on the Damaged Characteristics of the Shaped Reflector Antenna

摘要: 利用物理光学法分析了赋形双弯曲反射面天线在冲击波形变效应和破片打洞效应影响下远区辐射场的变化。由测试结果建立了反射面形变的数学模型，推导出了远区辐射场的计算方法，并提出了反射面打洞的模型及其辐射场的计算方法。结果表明：形变的位置和大小对天线辐射方向图的影响是不同的，破洞的位置和大小对天线辐射方向图的影响也是不同的，文中给出了详细的对比结果。

Abstract: PO(physical optics) method is applied to calculate the radiation pattern of the distorted shaped reflector antenna and the reflector antenna with a hole. The reflector distortion model is established by using the testing results. The simulation results show that the radiation pattern becomes degraded as the position and size of the distortion and hole are changed.
