Analysis of terahertz wave scattering characteristics of unstable rough surface target
摘要
Abstract
The scattering characteristics in terahertz band of uniform partition and non-uniform unstable conducting target with different roughness surface is studied.This paper proposes to apply the modeling concept of randomly rough surface to the modeling of uniform partition and non-uniform unstable rough surface target in terahertz band,which is different from the model-ing method of using formulae.Two physical quantities which are used to describe the RMS height and correlation length of rough surface are applied to adj ust the roughness of target surface.Firstly,the rough surfaces of uniform partition and non-uniform un-stable target are modeled by Gaussian random surface,then a combined method of physic optics and equivalent current is em-ployed for simulation.The THz wave scattering characteristics of different rough surface target with different incident angles,dif-ferent frequencies and different roughness are analyzed and discussed.Finally,the relevant conclusions are drawn.关键词
