中文摘要：

提出一种基于几何光学法的精确计算粗糙表面的辐射特性的研究方法，研究了半球漫入射一维余弦粗糙面情况下，离散网格数目和方向离散数目对计算精度的影响，分析了粗糙面的粗糙度和相对尺度，及一次、多次散射分别对出射方向辐射强度的影响，解释了不同粗糙面中的散射增强现象。

英文摘要：

A precise method based on geometric optics method was developed to study radiative prop- erty of rough surface. Effect of numbers of discrete grids and directions on the computation accuracy was investigated with diffuse incidence into one dimensional cosine rough surface among a hemispheric solid angle. And the influence of roughness and correlation length, one- and multi-scattering of rough surface on the outgoing angular radiative intensity was also discussed; the scattering enhancement of energy within different rough surfaces was explained.
