Abstract
Here we describe an efficient mathematical model of polarized radiation transfer for the purposes of passive polarimeters operation. The model is built upon a new approach to the solution of a vectorial radiation transfer equation (VRTE) boundary problem based on the subtraction of VRTE solution’s spatial singularities by means of the vectorial small angle modification of spherical harmonics method (VMSH) with the subsequent determination of the solution’s smooth part. The atmosphere is considered as a slab of an arbitrary thickness. The angle of irradiance is arbitrary and a diffusely reflecting bottom boundary with variable reflectance was admitted. We explore the influence of the turbid media upon the spatial distribution of the polarization state of reflected or transmitted radiation by both changing of scalar parameters (single scattering albedo, optical thickness of a slab, average scattering cosine or the maximum degree of polarization state and elasticity within single scattering act for Heneye-Greenstein (HG) scattering model) and the substitution of different scattering matrix models: HG, Rayleigh, Mie.
