ABOUT THE GEORADAR-EXPERT

Over the past decades, the method of georadiolocation has surely taken its rightful place among non-destructive methods of research and monitoring of subsurface media. A lot of positive experience has been accumulated, both in field work and in the processing and interpretation of georadar data.

Along with the undoubted merits of georadiolocation, there are limitations of this method. If on the ground-penetrating radargram we see reflections from the boundaries of subsurface media with different electrophysical characteristics or from some other objects in the ground, we understand that this radargram is informative. We know that the reflections will be visible only if the electro-physical characteristics of the medium change abruptly. But what will we see on the radarogram, when the electro-physical characteristics of the subsurface medium will change gradually smoothly enough? We will not see the boundaries and will not be able to get an idea of the structure and features of the soil (or features of some other object of georadar research, concrete slab or a road covering, for example).

To solve this, and a number of other georadiolocation problems, we have created the GEORADAR-EXPERT software. In this software, both traditional methods of digital processing of GPR signals and the method of automated analysis of the backscattering electromagnetic field (BSEF) are realized. The BSEF analysis method allows obtaining information about the structure of the subsurface medium even when the electro-magnetic characteristics of this medium change sufficiently smoothly to not form reflections from the boundaries between the layers in the radargram:

The method of automated analysis of BSEF has the following advantages:

  • The depth of the georadar survey is increasing, since the data processing algorithm in the GEORADAR-EXPERT software has high noise immunity;
  • One can see changes in the electrophysical characteristics within the layers and in the transition zones;
  • There is a significant increasing in the informativeness of georadar surveys;
  • The processing speed of GPR data is significantly increased, which is important for the constantly increasing volumes of georadar surveys;
  • There is an expansion of the scope of application of the georadar;
  • The influence of the so-called human factor is minimized;
  • There are more opportunities for investigating compound subsurface environments.

The graphical user interface of the GEORADAR-EXPERT software is a combination of tabbed panels. This allows you to quickly switch between visualization modes and control panels for processing GPR data.

Along with the analysis of the BSEF, the whole set of standard procedures for processing GPR data is implemented in GEORADAR-EXPERT software: various types of signal filtering, layer boundary tracing, increased resolution of georadar data, and much more.

For an area georadar survey, it is possible to visualize 3D environment parameters and wavefield attributes for GPR profiles of unequal length and arbitrary orientation.

The user can manage already existing orthogonal cross-sections of the 3D assembly, create their own sections, save them to a file and load them from the file:

In 3D mode, all the necessary options for visualization of a 3D array of georadar information are provided, including the possibility to make the specified range of the 3D assembly attribute values transparent, which allows one to observe the shape and position of one or another anomaly:

In 2D mode, as in 3D mode, you can make the specified range of attribute values invisible:

Visualization of the boundaries of the layers in the form of isosurfaces clearly shows their position in space:
