PIPE SEARCH

The figure below is a screenshot of the GEORADAR-EXPERT software with an open tab of the georadar profile display. The profile crosses a plastic pipe of small diameter. Diffracted reflection from the pipe is difficult to detect among the numerous reflections from the inhomogeneities of the man-made soil in which the desired pipe is located.

The following figure shows a section of dielectric permittivity constructed on the basis of an automated analysis of the backscattering field (BSEF). The area of the plastic tube is brightly displayed on the section. The dark line on the section is the outsole of the fill-up ground.

DETECTION OF UNDERGROUND COMMUNICATIONS

Figure 1 shows a fragment of the terrain plan with a GPR profile (a red arrow, the length of the arrow corresponds to the length of the profile) passing over the metal conduits. The georadar survey was carried out with a GPR with an antenna unit with a center frequency of 250 MHz probing pulses. The task of the survey is to clarify the situation of water conduits.

Figure 2 shows a radargram obtained in the course of GPR profiling. Because The georadar moved along the snow cover, on the radarogram there are interference signals from signals from the boundary of contact of the snow thickness with the ground surface. Reflections from water conduits on the wave pattern of the profile are not visible. The removal of interference by various methods of digital signal processing, including the subtraction of the average with a minimal window, did not lead to positive results.

Figure 3 shows the section of the attribute "Specific Electrical Resistance", created in the GEORADAR-EXPERT program based on the results of the automated analysis of the backscattering field. Yellow-red colors are displayed areas of the section, which correspond to the position of the water pipes crossed by the GPR. As a result of the treatment, the water pipes are clearly displayed on the section, when they are practically not visible on the profile PR04.
