摘要
文中根据所推导的植被方向散射系数和双向散射系数的解析表达式,具体计算了植被双向反射率.通过计算考查了植被形态结构对其双向反射率的影响,并讨论了植被双向反射率随太阳方位及观测方位变化的规律.
Based on the analytical forms of directional and bidirectional scattering coefficients,thebidirectional reflectance of a vegetative canopy is calculated.The influence of morphology onthe bidirectional reflectance is considered.Also,the variation of the reflectance with the az-imuth angles of sun’s incident and exit light vector is studied.
