飞航导弹的电磁散射特性分析

Analysis of Electromagnetic Scattering Character for Winged Missile

对橄榄型弹头导弹的结构进行了简化,建立了导弹的电磁散射模型。通过综合运用等效电磁流法(MEC)、几何光学法(GO)以及物理光学法(PO)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);并且考虑到各散射场之间的相对相位关系,计算了橄榄型弹头导弹整体雷达截面积,其结果与相关文献的测量值吻合较好,说明了文中的分析方法是正确、有效的。

In this paper,the configuration of olivary warhead missile is simplified and the dectromagnetic scattering model is built.High-frequency methods,including method of equivalent currents (MEC),geometrical optics(GO) and physical optics (PO),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 result is in accor- dance with the measured results given by references,which shows the analytic method is right and valid.
