This paper studies parameters of the snow-ice cover and forest ground using the integrated approach based on global navigation satellite system reflectometry. The results show that by analyzing the amplitude and time response of satellite navigation signals, along with numerical simulation and local weather data, it is possible to evaluate the current state and predict the dynamic development of these layers.
The paper studies parameters of the snow-ice cover and forest ground determined by the integrated approach based on the global navigation satellite system reflectometry. Experimental data on the amplitude and time response of satellite navigation signals are processed by fast Fourier transform and then analyzed using mathematical methods based on the multipath echoes model in terms of geometrical optics. Using a combination of reflectometry and numerical simulation of the surface layers based on local weather data, it is possible to evaluate not only the current state of these layers, but also predict their dynamic development.
