This paper discusses the analytical way of decomposing the remote sensing digital imagery. The method canseparate all the components (including the straight light

the sky scattering light and the brightness of the atmosphere)which form the original image information. Every component will generate a new digital image. These images are theresults of the interaction between all the components and the atmosphere

and objects

so

they have distinctive effect inthe remote sensing quantitative inversion searching for the earth's surface radiant energy and the state of environmentand pattern recognition of remote sensing pictures.
