Investigation of Reservoirs Ice Covers with Different Salinity Using the GNSS Reflectometry
https://doi.org/10.1134/S1062873824709371
In the period from winter to spring 2024, a series of measurements of interference reflectograms from layered structures of ice surfaces of freshwater and salt reservoirs of the Krasnoyarsk Territory and the Republic of Khakassia were carried out. These measurements were performed using signals from navigation satellites operating in the L1 band. The experimental data obtained in the form of amplitude-time dependencies were processed using the fast Fourier transform algorithm. Subsequent analysis of the measurement processing results allowed us to conclude that the GNSS reflectometry method is highly sensitive to determining the macrophysical characteristics of ice surfaces with different salinity of reservoirs.
