Abstract

The possibility of separate estimation of soil moisture and surface roughness is considered, and the results of numerical simulations are presented. It is shown that the use of multifrequency and dual polarization radar methods permits to estimate the dielectric constant of soil, r.m.s values of roughness and spatial correlation radius. It is demonstrated also that a fractal approximation of the surface spatial spectra enables to obtain the most accurate estimation of soil surface parameters. Experimental results for 3.0 and 0.8 cm are presented as well showing the possibility of dual-polarization data processing for land erosion degree determination
