Abstract

A multicomponent approach to calculate a light field structure with allowance for multiple scattering in the media such as clouds, mists and ocean water is given. All characteristic properties of the real phase function are regarded and propagation in a scattering medium of any optical thickness with an arbitrary single scattering albedo can be considered. The phase function is represented as a sum of more simple functions. The radiance is given as a sum of appropriate components. The equations like the radiative transfer equation are obtained for each component. They can be solved using the known methods within domains where they work best of all. Comparison of various solutions (lidar returns, temporal structure of light pulse transmitted by cloud, an angular structure of the light reflected from and transmitted by cloud) with different numerical calculations shows a fairly satisfactory accuracy of our analytical formulas.
