For successful interpretation of ground penetrating radar data, it is desirable to obtain signals with a large amplitude, but so that they do not have amplitude limitations. To study the upper part of the section, attenuation is used. Usually, the entire section from top to bottom is studied fragmentarily. The method described in the article allows one to construct a complete picture of the section along the entire depth based on the survey results. The algorithm for constructing a section based on data with a set of attenuations shows a significant increase in the dynamic range (signal/noise ratio). The practical significance of the method lies in obtaining a complete picture of the section from top to bottom with detailing along the entire depth.
