中文摘要：
实验测量了某种卫星包覆材料和太阳能电池板样片在可见光波段（400～780nm）的光谱双向反射分布函数．将样片的光谱双向反射分布函数对可见光波段内的太阳谱辐射照度加权平均，获得了可见光入射时目标样片表面的平均双向反射分布函数，并利用遗传算法建立了其参量化统计模型．应用此模型，结合目标的几何建模、消隐，计算了可见光入射时某卫星散射光强度的空间分布，并分析了其与卫星的几何形状、表面材料等的关系．
英文摘要：
The spectral bidirectional reflectance distribution function of some satellite coating materials and solar panel samples were measured in the visible spectrum （400 - 780 nm）. Average bidirectional reflectance distribution function of samples illuminated by the sun were obtained by weighted averaging the spectral bidirectional reflectance distribution function data over the spectral irradiance in the visible solar spectrum,and their parameterized statistic models were obtained with the genetic algorithms. Using the model,the spatial distribution of sca.ttering light intensity reflected from the satellite is calculated with the modeling and blanking technique of targets when being illuminated by the sun, and its relations with the geometry, materials and other attributes of the satellite was analyzed.
