Abstract :
In this paper, we study the impact of multiscale description of rough surface on the radar backscattering using the small perturbations model which is used when the surface height standard deviation is much smaller than wavelength and the rms slope s is not high. This sensitivity analysis gets an inverse model of the backscattering model in order to retrieve the roughness and soil moisture parameters.
