This study investigates possibilities for identifying additional deposits of polymetallic ores based on geophysical studies that use ground-penetrating radar (georadar). Such studies can render a deposit significantly more attractive from an economic standpoint. Experimental methodological work was carried out to compare the geological data of preliminary exploration and georadar exploration with GROT 12 georadars.

The article describes the correlation between the signal edge amount of sounding pulse and small irregularities detection in environments with dispersion. The analysis of experimental data on effective bandwidth of decameter waves spreading on the route Moscow-Ekaterinburg and results of wideband ground-penetrating radar sounding in natural environments with high dispersion gives the opportunity to experiment on surface, vertical and backward-inclined sounding. It is reported that the use of wideband electromagnetic pulses is perspective trend of progress in sounding of natural environments.
