摘　　要：为研究导弹目标的电磁散射特性,预估和优化导弹系统整体设计,分析了导弹的高频散射机理,并且运用物理光学法计算目标表面反射场的RCS,以及等效电磁流法计算由弹翼的前后沿、弹体结合部及弹尾产生的边缘绕射场的RCS。用算法对某已知导弹弹体模型进行仿真,与文献中验证过的结果吻合,且方法运算速度快,不受目标尺寸约束,完全可以满足工程分析的需要。根据某型导弹的设计要求,对其进行了建模,并给出导弹模型及仿真结果。In order to investigate missile＇s electromagnetic scattering, preestimate and optimize integrated missile system, scattering effect of missiles was analyzed. Physical optics （PO） was used to calculate RCS of reflecting field, and equivalent currents （MEC） were used to calculate RCS of diffraction caused by front and back edges of wings, joint part of the body and trail of missile. Simulation was carried out using some known missile, which proved that this algorithm can satisfy the analysis need for the RCS calculation of missiles. Therefore, a model was established for a certain type of missile based on its design. And missile＇s model and simulation result were presented.
