摘要: 给出了平行和垂直极化平面波投射到物体时散射场的通用表达式,阐述了确定目标主要回波源位置的方法,提出选取吸波材料涂敷区域的有效方法,同时分析了局部涂敷吸波材料(RAM)的复杂目标电磁散射特性的计算,最后给出计算结果,并经验证.这种方法提高了复杂目标雷达散射截面计算的精度,适用于工程应用.

Abstract: The general formulas of the scattering field when the parallel and vertical polarization plane wave incident on the objects are given.The method of determining the strong scattering source of complex objects,and the effective method of selecting region coated with radar absorbing material(RAM) are presented.At the same time,the electromagnetic field scattered from three dimension complex objects partially coated with RAM is analyzed.At last,the calculated results are given,and the validity was tested.The method improves the calculation accuracy of complex RCS,and is fit for the engineering application.
