Previously, you sometimes needed to preprocess a GPR profile before performing a BSEF analysis. Now pre-processing is no longer needed, except when the GPR profile is recorded with an excessively small profile step compared to what is recommended in the User Manual. In this case, to bring the GPR profiling step to the recommended value, you need to decimate the GPR profile horizontally using the appropriate tool implemented in GEORADAR-EXPERT.

Excessively large GPR profiling step (distance between GPR traces) leads to the absence of the diffraction component of the wavefield on the GPR profile. Previously, this was an obstacle to correct BSEF analysis. Now, as a result of implementing the new algorithm for automated BSEF analysis, there is no such problem. Now, with the help of the automated BSEF analysis, it is possible to correctly process GPR data obtained as a result of GPR profiling with a large step.  

The algorithms for the automated calculation of the default available corrective functions used to minimize BSEF analysis errors have changed. The number of varieties of these functions has also changed. Now it is easier to choose the type of corrective functions. The variants of section creation settings that do not require correction of BSEF analysis results, and therefore do not require the use of a corrective function, have become more common.

The principle of creating corrective functions in manual mode has changed. Sliders are now used to fine-tune the shape of the corrective function, which makes the process of creating a corrective function easier. Also, you can divide the GPR profile into fragments, and define a different type of corrective function for each fragment.

There are new tools for colormap editing, allowing you to change the colormap using sliders and specialized controllers, as well as by dragging the colormap fragments to a new location in the colormap.  All these tools allow you to effectively upgrade already ready colormaps, which are available by default, to visually highlight one or another element of the section, depending on the task of GPR survey.

The generator of random colormaps was modernized. In its algorithm, it is added taking into account the ratios of elements of a randomly created colormap to correct this map in order to create high-contrast colormaps, or vice versa, colormaps with soft color changes, which are well suited for visualizing a section in the fill mode between contours.

The graphical user interface of the GEORADAR-EXPERT software system has changed, especially in terms of managing the settings for creating an attribute section. In connection with this, the GEORADAR-EXPERT User Manual has been significantly changed, especially the chapters of the manual dedicated to automated BSEF analysis.
