Analysis on the Radar Scattering for the Boss at the Position of the Metal-Medium Connection of Aircraft Cabin

通过对凸台型结构目标的电磁散射特性分析 ,利用棱边绕射和模式波耦合的方法计算了凸台的二维和三维RCS值 ,并在此基础上对飞行器座舱的金属 -介质连接结构的雷达散射特性进行了分析和计算。计算结果和文献结果符合较好 ,此项研究对整机RCS的计算有重要意义。

Diffraction analysis is presented due to a material discontinuity formed by the junction of a thick dielectric half-plane with a metallic one having the same thickness. This is accomplished by first considering the solution of several subproblems. These include the direct diffraction and coupling due to a plane wave incident on a loaded open-ended parallel plate waveguide and those of radiation and reflection by a waveguide mode. Take advantage of the result, we calculate the metal-dielectric join on cabin of the aircraft, the final result satisfied that of the document's。\;
