Abstract. GPR method began to develop from the middle of the twentieth century and by the end of the century was effectively applied in solving some geophysical problems in the upper layers of the earth's surface. With the exception of the thick ice sounding in the polar regions, however, the method was effective only in studying the first tens of meters of natural media with low absorption of electromagnetic waves. For the further development of the technology an increase of the penetration depth is crucial.

The influence of the shape of the transmitted pulse on the penetration depth and resolution of the GPR method is analyzed. The features of constructing radar devices for subsurface sensing of media with high attenuation and dispersion are discussed. Design features of radar devices for subsurface sensing of media with high attenuation and dispersion are discussed. It is noted that the theory of interaction of video pulses with absorbing disperse media is currently not sufficiently developed for many applications. The lack of developed theory about the model of interaction of video pulses with absorbing media with high dispersion complicates the solution of the inverse problem of reconstructing the medium parameters from experimental GPR data.

Experimental results obtained during GPR studies at depths of more than 100-500 meters in Yakutia are given. The advantage of using high-voltage video pulses for the study of natural media with high attenuation and dispersion is confirmed. Quantitative estimates of the attenuation of the video pulse signal made for media with different lithological composition. The results obtained can serve as an experimental basis for creation of local radio communication systems and radiosounding of disperse media with high attenuation.

Key words: GPR, video pulse, dispersion media.
