摘    要:应用物理光学法(PO)与等效电磁流法(ECM)分别计算了复杂目标双站散射中面元与棱边的散射场。在WINDOWS NT/98微机平台上利用软件图形标准接口Open GL和硬件图形加速卡对目标和背景像素进行实时显示和自动消隐,通过对各像素点的散射场计算和要位综合求得总散射场,从而将GRECO扩展为双站图形电磁学。数学模型和实例说明了本方法的正确性,对**战斗机双站RCS进行计算,对将来虚拟现实系统环境

关 键 词:电波散射  雷达散射截面(RCS)  双站图形电磁计算

Abstract:Based on PO & EMC methods the EM scattering characterization of bistatic RCS for facets and wedges ofcomplex targets is presented in this paper. IN WINDOWS NT/98 platform, the bistatic Graphical Electromagnetic Computingmethod is presented by using the Open Graphical Library and synthesis of the facets and wedges. The mathematical model andpractical example are given to verify the validity of the method. At the same time, it gives bistatic RCS curves of a complextarget for a practical case in virtual reality environment. The results have practical engineering value.
Keywords:electromagnetic wave scattering  radar cross section (RCS)  bistatic GRECO
