The experimentally recorded amplitude-time dependences of the interference superposition of signals from navigation satellites and their copies reflected by the boundaries of the "atmosphere-water" and "atmosphere-land" media are presented. Fourier spectra of these dependences are obtained. It was found that for different electrophysical properties of reflecting surfaces, noticeable features of the spectra appear. Keywords: GNSS reflectometry, surface, interference, amplitude-time dependence, Fourier spectrum.
