摘要 采用矩量法计算狄利克莱边界条件下一维高斯型随机粗糙面的收发分置的散射系数,运用脉冲基函数和点匹配的矩量法,在入射波为锥形波的条件下,分析了两种频谱函数下的仿真结果。结果表明,该随机面仿真粗糙导体面效果较好,为电磁环境建模提供了一种方法。 In this paper, the Bistatic scattering coefficient from one - dimension Gaussian perfect conductor random rough surface is computed by the Moment method in Dirichlet boundary condition, and the basis function is taken as the pulse function and weighting function in the point matching method. A tapered incident wave is applied. By this method, two different spectrums in rough surface are analyzed. The results prove that the simulation of rough conducting surface with Gaussian surface is better in effect, which is a good method of modeling in electromagnetic environment.
