摘要
将入射平面波展开成一系列三维复射线波束场，分析各波束经过多层介质雷达罩的透射与旋转抛物面天线反射后，提出了一种等效复射线源来得到最终散射场的方法。设计了反射与透射的通用自动追踪程序，可进行天线和无线罩一体化的雷达载面（ＲＣＳ）分析，给出了一个数值计算实例。
The incident plane wave is expanded into a series of fields of three-dimensional complex rays,the penetrations of rays through a multilayered radome and the reflections of rays through a reflector antenna are analyzed,and the resultant scattered fields are obtained by a complex ray equivalent source method.A general automatical searching program for reflections,refractions,and penetrations is designed and can be used for RCS analysis of an antenna and a radome. A numerical example is also given.
