Scattering and emissivities of oblique incident waves from double-layered random rough surfaces in remote sensing of snow

In this paper it is studied for 2-D scattering and emissivities of oblique incident waves from double-layered random rough surfaces. At oblique incidence, the cross-polarization scattering is presented for double-layered snow surfaces with large heights and large slopes. Numerical results show that the cross-polarization results can be large to degree of those of co-polarization at a large oblique incident angle. All four Stokes parameters are also calculated for polarimetric passive remote sensing of snow layered media. The Stokes parameters presented in this paper are compared with the previously published results with periodic boundary condition, and the artificial kinks and abruptions imposed by Floquet models are removed in this new model.
