摘要 从无限大衬底任意吸波材料表面等效电磁流出发,通过对电大尺寸任意形状多边形逼近,从理论上推导得到了部分涂覆导体目标电磁散射物理光学法的快速计算式,该表达式中全部是代数运算,无须积分,因此具有很高的计算效率,为快速估计电大尺寸部分涂覆导体目标的雷达散射截面打下了基础. A rapid evaluation formula for the PO method on electromagnetic scattering by arbitrary shaped conducting targets with partial coating is obtained by approximating electrically large scale objects with polygons, based on the theory of equivalent currents on the arbitrary RAM surface with the infinite metal substrate. It makes the calculation high efficient as there are only simple algebraic operations without integration in our formula. This establishes a basis for the RCS rapid evaluation of the electrically large scale conducting bodies with partial coating.
