摘要
提出了一种结合图形电磁计算直接计算目标双站RCS的新方法。通过读取物体表面相对于入射方向和相对于散射方向的深度值,完成了对能产生散射场和绕射场的面和棱边的识别;修正了几何绕射场存在物理光学重复计算的问题,引入了物理绕射系数和等效电磁流相结合的方法。实例表明本文方法计算结果与文献结果吻合,从而证明本文方法的有效性。
A new method of computing bistatic RCS with Graphical Electromagnetic Computing is presented. The faces and edges, which are able to generate a diffracting field, can be detected by attaining the depth value of the faces of the targets relative to the incident direction and diffracting direction. The error of the Physical Optics field of edge, which is computed twice, has been corrected by using Physical Theory of Diffraction. The method of combining PTD with ECM is used in the disquisition. The result of using this method is the same as that showed in the documentation, which has proved that this method is effective.
