INFLUENCE OF SALINITY ON DIELECTRIC PROPERTIES OF MOIST GROUND AT POSITIVE AND NEGATIVE TEMPERATURES

Abstract

An experimental study was made of the indices of refraction and absorption of sand and bentonite in the decimeter wavelength range as a function of water content and temperature. The influence of salinity on the behavior of their dielectric properties at negative temperatures and upon a transition through 0°C was studied. The results indicated that it is possible to carry out radiometric remote sensing of soil salinity during the winter.
