Abstract
The characteristics of snow backscattering in microwave band are considered. It is shown that they depend upon many parameters describing the state of snow cover. The basic dependences obtained from theory of radar backscattering and experimental data are discussed and compared. Real radar remote sensing data for different dates in fall/winter period are presented for Eastern regions of Ukraine. It is demonstrated that the effects predicted theoretically are observed for remote sensing images obtained from side-look radar installed on the satellite “Ocean”. It is also shown that remote sensing means in some conditions permit to get the maps of snow cover thickness but in this case the reference data from several on-land meteorological stations are needed for calibration purposes.
