摘　　要：结合微分长度绕射系数和一致性等效电磁流推导得到了微分边缘绕射系数 ,将任意观察方向上的远区散射场与任意方向入射的平面波以绕射系数形式联系起来 ,得到一种实用简便的高频散射计算方法。并以多边形平板为例验证了该方法。In this paper, the increment edge diffraction coefficient is achieved through the increment length diffraction coefficient (ILDC) and the equivalent electrical current method(MEC), and the far fields in an arbitrary azimuth angle is related to arbitrary incident field through the derived diffraction coefficient, so that the high-frequency scatted field can be computed conveniently. The arbitrarily shaped conductor polygon plate is analyzed to demonstrate the effectiveness of the presented method.
