摘要
运用改进型菲涅尔方程和基尔霍夫近似方法分别研究室内不同粗糙面的太赫兹波反射和散射。根据改进型菲涅尔反射理论,得到了在水平和垂直两种极化状态下,不同入射角、不同粗糙面及不同频率的反射系数,分析了以上参数变化对反射系数的影响和物理意义。同时,基于基尔霍夫近似理论,得到了在水平和垂直两种极化状态下,不同入射角和方位角、不同散射角、不同粗糙面的散射系数,获得了散射系数随以上参数变化而产生的数值结果,并分析了仿真结果的物理意义。
The modified Fresnel equations and Kirchhoff Approximation method are adopted to analysis theoretically reflection and scattering from indoor rough surface, rest^ctively. According to the modified Fresnel equations, The horizontal and vertical polarization reflec- tion coefficients for different rough surface cases are obtained. Meanwhile, according to Kirchhoff Approximation method, the hori- zontal and vertical polarization scattering coefficients for different rough surface cases are obtained. Finally numerical illustrations are usod in reflection and scattering coefficients, and physical meaning of simulation resuhs arc analyzed.
