【摘要】 采用矩量法(MOM),分析了多光束在分形粗糙导体表面的散射分布·对在不同入射角、光束宽度控制因子、光束照射区宽度、表面均方根高度和表面分维数情况下的散射进行了数值仿真·仿真结果表明了各参量的变化对散射分布的影响·根据仿真计算结果给出了最佳的散射测量区域,为减少多光束测量的误差提供了一定的参考·更多还原

【Abstract】 Multi-light beam scattering from fractal rough surface based on method of moment was studied.In order to investigate scattering field of multi-light beam with different incident angle,the tapering parameter,illumination region,rms height and fractal dimension,and numerical simulation were carried out.The results of simulation show some relationship between distribution of scattering field and these parameters.It could provide reference to decrease the error for multi-light measurement.更多还原
