Abstract
The paper presents the results of reflectometry data processing for ice surfaces using navigation satellite radio signals. A fast Fourier transform (FFT) procedure was used to process the obtained amplitude-time dependences. The results and processing methods allowed us to identify functional relationships between ice thickness and the altitude of the navigation receiver's phase center, the navigation satellite's elevation velocity above the horizon, and the characteristic frequencies identified through Fourier transform analysis.
