论文摘要
使用Ray-Optics近似研究研究了自伴均匀的各向同性随机粗糙表面的光散射。开发数值方法是为了加快表示为单连接的单值随机场的表面的一阶散射模拟，并将模拟的结果存储到数值反射率模型中。开发了地平线映射和行进方法以加速模拟。重点是几何阴影和掩盖效果，尤其是表面粗糙度的函数，尤其是方位角粗糙表面阴影效果。
Light scattering from self-affine homogeneous isotropic random rough surfaces is studied using the ray-optics approximation. Numerical methods are developed to accelerate the first-order scattering simulations from surfaces represented as single-connected single-valued random fields, and to store the results of the simulations into a numerical reflectance model. Horizon mapping and marching methods are developed to accelerate the simulation. Emphasis is given to the geometric shadowing and masking effects as a function of surface roughness, especially, to the azimuthal rough-surface shadowing effect.
