摘　　要：利用3DMAX对目标进行几何建模,输出3ds格式的数据文件,物体表面用三角面元模型描述并网格划分,构建风云卫星模型.结合基尔霍夫近似理论对常见典型物体及风云卫星模型的光散射角分布进行了计算,得出了不同形状的特征信息,并得出风云卫星不同部位的光散射特性与材料参数的关系.The model of complex object is built by use of 3DMAX, obtaining data file of 3ds style. The fly-1 satellite model is constructed and its surface is consistent of triangular facets and grid generation. The light scattering of typical objects and fly-1 satellite model are calculated with Kirchboff approximate theory. The characteristic information of scattering depends on the shape of objects. The scattering character of fly-1 satellite is related to different material parameters and the relation of them is drawn.
