摘要
提出利用等效边缘电磁流方法快速计算复杂形体电大尺寸目标的双站RCS。该方法运算速度快 ,考虑了边缘绕射和遮挡 ,计算精度高。在计算尖锥柱等典型散射体的 RCS的基础上 ,计算了一导弹模型在不同方位角下的双站 RCS,证实了本方法的可行性。
The equivalent edge elctromagnetic currents method (EECs) was presented to study the electromagnetic (EM) scattering from the electrically large conductive target. This method is characterized by faster in calculation, thinking over the diffraction and shelter from edge, and high accuracy. Based on the RCS of typical targets, the bistatic RCS of a missile model was calculated, demonstrated the applicable of this technique.
