In remote sensing imaging, there are two factors, which cause differences in radiation under different imaging mode, the first reason is the atmospheric transmission, and the second reason is difference of reflection in ground objects. For the atmospheric transmission, a lot of atmospheric transport models have been proposed, and some professional atmospheric correction software have been released. For the reflection difference, researchers need to study the light reflectance characteristics of

Based on measurement result of reflectance, this paper adopted an improved bidirectional reflectance distribution model and derive coefficient suitable for the cement ground from parameter fitting. The calculated data of relative reflectance distribution using improved theoretical model are more similar to measured results, and the model is suitable for asphalt ground also.
