Abstract
Physics-based Fully-Coherent Electromagnetic (EM) scattering model from 3D snowpack with arbitrary thickness is considered. The computer-generated snow media is reconstructed using the implementation of the Lineal-Path function in conjunction with 3D spatial exponential correlation function to assure the macroscopic connectivity of the snow particles. A fully-coherent EM computation is performed using the Statistical S-Matrix Wave Propagation- in Spectral domain approach (SSWaP-SD) along with a Method of Moments (MoM) code based on the Discrete-Dipole Approximation (DDA). This approach is chosen to leverage both the time-efficient computations of the DDA and the full-coherency of the SSWaP-SD method simultaneously. For an arbitrarily thick snow layer, thin slabs of a snow pack is analyzed a corresponding polarimetric N-port (representing different directions of scattering) S-matrix is generated. These S-matrices are cascaded using SSWaP-SD method to calculate the total forward and backward bistatic scattered fields in a fully coherent way. The simulation results of the backscattering from an arbitrary thick snow layer are presented.
