摘　　要：文章给出了一种多层材料覆盖的卫星目标雷达散射截面的建模与计算方法,并利用该方法对理想导体的立方体和圆柱体进行仿真验证。最后给出了卫星目标RCS的计算实例,对比了纯金属材料的卫星体与多层材料覆盖的卫星体RCS的结果。In this paper,a modeling and calculation method for the Radar Cross Section（ RCS） of complicated satellite targets is introduced,and the method is applied to the calculation and simulation of cube and cylinder with perfect conductor characteristic. Finally,the calculation instance of satellite target RCS is realized,and the result is contrasted to the satellite with metal material. The conclusion is that the method adopted in the paper can simulate the message of dielectric surface and effectively and fleetly calculate the RCS of multi-layer material for complicated targets.
