Estimation of Remote Sensing Characteristics of Salt Wet Soils at Decimeter Wavelengths

Abstract

The numerically simulated effect of salinity of wet soils on their radar sensing characteristics in L- and P- bands are shown for the circular – also, for comparison, the linear horizontal – polarizations. The saline soil detection in active remote sensing in the L-band is shown to become imperfect due to the influence of a vertical profile of soil humidity distribution. The difference between L- and P-band scattering by wet soils and the applicability of active remote sensing techniques in the decimeter wavelengths for estimation of the soil salinity are discussed.
