The Approximate Mathematical Models to Compute the Spatial-Frequency Characteristics in Problems of Nonuniform Surface Remote Sensing

The approximate mathematical models to compute the spatial- frequency characteristics (SFC) for the transfer problem above a reflective surface constructed. The finite plane-parallel vertically inhomogeneous absorbing-scattering slab with nonuniform Lambertian's and non-Lambertian's anisotropically reflecting boundary is considered. The invariant SFC are computed as a solution of the one-dimensional parametric complex-valued equation. The V.V.Sobolev's approximation is deduced from the formulated models. The boundary condition was stated.
