Abstract:
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:
