Radar dual-polarization remote sensing of soil erosion

The results of experiments for soil erosion determination with the use of dual-polarization radar set at wavelengths of 3 and 0.8 cm are presented. It is shown that the specific radar cross-section (RCS) is a function of soil erosion at the range of incidence angles from 35 degrees to 60 degrees. The sensitivity of soil backscattering to erosion is more high when the ratio of RCS for HH and VV polarizations is used. The best description of surface roughness spatial spectra is fractal one. The results of image processing obtained by airborne radar remote sensing system of K u -band with dual- polarization reception are discussed and the comparison of results of soil erosion determination by radar remote sensing techniques with in situ measurements is made.
