| 摘 要： | 依据目标表面材料光谱反射率、等效光学常数色散曲线和双向反射分布函数（BRDF）及表面高度起伏均方根,建立了理论模型,计算分析了一种空间简单体组合模型在太阳、地球-大气系统背景影响下目标可见光散射特性随入射波长和轨道高度的变化关系。计算结果表明,散射体在相同轨道的条件下,表面材料的反射率越高,光散射强度越大;散射体材料相同时,散射体散射强度随着散射体轨道高度的增加而减小。

| Abstract: | According to reflectivity spectrum,equivalent optical constant dispersive curve,BRDF,and the root mean squared of the surface material of target,the theoretical model was established.The changing relation of the visible light scattering for a simple space on orbit targets between wavelength and orbital altitude was calculated and analyzed.The results showed that the reflectivity of space targets material is higher,and scattering intensity will be stronger under the same orbit;in the other hands,the scatteri... |
