SAR Polarimetric Scattering from Natural Terrains
Abstract
Radar polarimetry and speckles of random rough surface scattering is studied using 3-D numerical solution of Maxwell equations (NMM3D) with surface size up to 32 x 32 squared wave- lengths. Proposed research is to model the rough surfaces which are characterized by exponential correlation functions. The rough surfaces are characterized by exponential correlation functions. The simulation results of cross- and co-polarization backscattering coefficients were in good agreement with experimental measurements of baresoils at L-band. Because in numerical solutions of Maxwell equations the electric fields of the scattered wave are calculated for each realization, scattering matrices can be simulated by NMM3D, and such simulations are performed in this paper. For a given RMS height, correlation length, soil permittivity, and incident angle, we calculated the radar scattering matrix up to 958 independent realizations.
