Abstract

The aim of this paper is to present a surface model inversion using the integral equation formulation of backscattering coefficients. A quantification of the influence of surface parameters such as roughness and soil moisture on polarimetric indicators for various frequency bands is led. Finally, a technique is introduced to retrieve a surface RMS height and dielectric constant from multi-frequency data. The inversion technique is applied to polarimetric and multi-frequency measurements acquired at EMSL, JRC laboratory.
