Abstract
The scalar time-independent equation of radiative transfer is solved in an iterative manner for the forward propagating radiance (specific intensity) distribution function. In the small-angle approximation, a close connection of the iterated series and the Wentzel summation method is established. When summed formally, the iterated series reproduces our previous results obtained by the method of characteristics. A new approximation scheme, appropriate for small scattering angles, is proposed. It is discussed in the context of the scattering by a random phase screen and by an irregular diffracting medium. Specific results, as well as comparison with other approximations, are presented for radiational and advective fogs. The method is also applicable for the computation of the backscattered reflected radiance.
