某型导弹的电磁散射特性分析

通过综合运用物理光学法（PO），等效电磁流法（MEC）和几何光学法（GO）等，并考虑目标各部分散射场间的相对相位关系，分析了椭球体和橄榄体两种不同形状弹头导弹的电磁特性，计算出了它们的雷达散射截面积（RCS）。计算结果与相关文献结论吻合较好，表明该方法更正确有效的，能满足工程分析需要。

Analysis of Electromagnetic Scattering for Some Type of Missile

In this paper, high frequency scattering theories, including physical optics (PO), geometrical optics (GO) and magnetic equivalent currents (MEC), were used for calculating the radar cross section of winged missile with ellipsoidal and olive warhead considering the relative phase contributions of scattering centers. The results of computation were in good agreement with the conclusions of the reference article. It is showed that the method was effective and could satisfy the analysis need for the electromagnetic scattering form winged missiles.
