This paper introduces a new method for atmospheric correction: BRDFAtmospheric correction Loop. Atmospheric correction was firstly performed by assuming that the groud is a Lambertian surface.By a series of corrected results of observed data Under different imaging geometric conditions

a model which can describethe most of these data was then found in the BRDF database.Finally

theatmospheric correction based on BRDF was carried out

according to the modellingparameters of the inversion. A number of experiments were designed

which haveproved the effectiveness and feasibility of this method.
