Paper Abstract

In this paper, we examine numerical solutions of the two- frequency radiative transfer equation to study pulse propagation through discrete random media. Specifically, we examine the plane-parallel problem using the Henyey- Greenstein phase function for scalar problems and Mie scattering for polarimetric problems. Since standard methods such as the discrete ordinate method and the finite element method are not numerically stable for polarimetric problems at large optical depths, we introduce a Chebyshev spectral method to solve these problems. Then, we examine a few examples of optical pulses in fog layers and millimeter wave pluses in rain layers, and compare our results to first- order scattering and diffusion approximations.
