Abstract
Reflectometric measurements of the ice surface conditions of reservoirs in the Krasnoyarsk Krai and the Republic of Khakasia are conducted using radio signals from navigation satellites emitting in the L1 band. During processing of the resultant reflectograms, mathematical processing of the amplitude-time dependencies is applied using the fast Fourier transform method, allowing for the experimental determination of ice cover thicknesses with various macrophysical characteristics.
