Radio echo-sounding is a powerful technique for investigating glacier subsurface. Various remote sensing techniques use different wavelengths (e.g., 13.575 GHz for CryoSat and 20-25/200-600 MHz for ground-penetrating radar), and the results gained using different wavelengths may not coincide but rather complement each other. Here we describe the electrophysical model of a cold glacier based on glaciological input data and radiophysical laws; calculate the depth profile of the dielectric constant, and track variations in the effective part of the dielectric constant and the loss tangent depending on the surface temperature and frequency of the radio signals; calculate the frequency dependence of the reflectivity coefficient of the modelled glacier; reveal the frequency range of radio-waves most suitable for investigation of glacier characteristics.
