| 摘 要： | 基于双向反射分布函数(BRDF),从太阳辐射理论出发,分析了表面漫反射率与入射波长的关系,卫星、太阳及观测站三者的相互位置关系.推导了卫星表面为朗伯表面和以BRDF模型为基础的随机粗糙表面的散射光照度表达式.然后以FY-1D卫星为例,计算了一段观测时间内,卫星地面照度值和视星等值的变化情况.最后比较了这两种条件下的地面...

| Abstract: | Based on the bidirectional reflectance distribution function(BRDF) and the basic radiation theory,the relations of the diffuse reflectance and the incident wavelength,and the position relations of the satellite,the sun and the observation point are analyzed.Based on the BRDF model,the formulations of the illuminance of the scattering light on the randomly rough surface are derived.And the result shows that the surface of the satellite is the Lambert surface.Subsequently,take FY-1D satellite for example,in o... |
