Statistical analysis of GPR profiling results provides information about attribute variability for the investigated section as a whole and for its individual structural elements. The analysis results can be used to identify relationships between the physical-mechanical and electrophysical properties of the medium, which are expressed through statistical indicators of attributes. 

The analysis is performed using 12 statistical indicators for the GPR profile, the attribute section, and the 3D assembly slice. The results are presented in tabular and graphical form. Threshold processing of data is implemented. In this mode, the areas of the graph that exceed or do not reach the specified level are highlighted visually, and their characteristics are summarized in a table. This approach is effectively used for detecting and documenting anomalies, for example, in diagnostics of pavement defects. 

An example of a graph of changes in the mean values of relative permittivity in the upper layer of the pavement is shown below. At the time of the survey, it was in a dry condition. On the right, below the graph, a section thumbnail with layer boundaries is shown. The layer whose data are displayed on the graph is highlighted with a fill. 

A threshold level is set on the graph. Values below this level are interpreted as indicators of pavement defects. The corresponding graph areas are highlighted in red. Below the graph, a table of the identified defect areas is shown. It contains the characteristics of each area. The table is saved automatically when the image of the statistical graph is exported.
