摘要
本文用几何光学理论、口径场积分和复射线理论对一端开口、另一端短路的矩形腔体进行了雷达散射截面的分析计算。说明了这两种方法在计算大口径开口腔体RCS的可行性。并将这两种理论的方法和结果进行比较。
In this paper, complex ray theory and geometric optics as well as integrating the aperture field are presented for calculating the interior radar cross section(RCS) from and openended cavity with rectangular cross section. It is convenient to calculate large, openended cavlties by this two methods, The comparison between the two approaches and results is alsopresented.
