Abstract:
One of the challenges of future planetary SAR missions will be the estimation of surface and subsurface geometric and dielectric characteristics. In this sense an analytical model of a two layer structure, with small scale roughness, is proposed optimized for lower frequencies. The model takes into account the distributed nature of surface and subsurface. The recovery of the sub-surface physical properties is discussed by means of 2 incident angles. Simulation results and noise robustness of the inversion model are shown.
