Accurate acquisition of the bidirectional reflectance characteristic of surface is essential foundation of radiometric calibration and satellite full-chains imaging simulation. Bidirectional reflectance distribution function (BRDF) is retrieved by measured BRF in field environment. The simulation result shows that the relative difference between the BRF directional coefficients of the same surface is 19% when atmospheric visibility is 15 km and 23 km, respectively. Therefore the true directional reflectance feature can’t be characterized by measured BRF in field environment due to the effect of atmospheric scattering. We propose a BRDF retrieval method, by the synchronous measurement of atmospheric scattering radiation in 2π solid angle. In this method, the residual between measured BRF and value calculated by measurement model is used as the cost function in inversion process, the effect of atmospheric scattering is deducted and the true BRDF parameters of surface are retrieved. The bidirectional reflectance characteristic is inherent attribute of surface and does not change with environment radiation.
