摘　　要：将导弹的结构进行简化,建立了其电磁散射模型,综合运用物理光学法(PO)、等效电磁流法(MEC)、几何光学法(GO)等高频方法计算了导弹模型各散射中心的雷达散射截面积(RCS),并考虑目标各部分散射场间的相对相位关系,计算了带橄榄型弹头导弹的整体RCS,其结果与文献的实测结果吻合较好,说明文中的分析方法是正确的、有效的。在此基础上,计算并分析了观测平面和极化方式对导弹高频电磁散射特性的影响。The configuration of missile was simplified, the electromagnetism scattering model of missile was built. Highfrequency techniques including physical optics （PO）, method of equivalent currents （MEC）, and geometrical optics （GO） were used to calculate the radar cross section （RCS） of various scattering-centers of this model. The total RCS of the missile with olive-shape warhead was calculated considering the phase contributions of scattering-centers, the results is in accordance with the measured result given by references. It is showed that the method is effective. Then, the missile＇s RCS under other polarization modes on different observation plane of missile was calculated, and the effect of observation plane and polarization modes on missile＇s RCS was analyzed.
