A principal breakthrough in georadar technology – ROTEG

Geodynamics, 2022
The purpose of the research was to verify the extraordinary big theoretical penetration depth of new developed georadar in the real conditions of karsts areas. The new kind of the Ground Penetrating Radar (GPR) – Roteg – was developed in 2013 (RTG-Tengler 2013).

Georadar for hydrogeology

55th EAEG Meeting, 1993
Falling water tables and deteriorating water quality are the major shallow hydrogeological problems currently facing groundwater management in the Netherlands; the former phenomenon is seriously affecting agriculture and nature conservation, where as shallow contaminated groundwater is a hazard for water supply companies and is also an environmental ...

Testing of a georadar in tunnel drifting

5th EEGS-ES Meeting, 1999
The radar [1] has been developed by Moscow Institute of Physics and Technology (MIPT) and joint stock company “Geological Prospecting” Rus. Ltd. Nine months, 3 days a week, the measurements of signals were carried out on the face and top of a tunnel, which is being built in Moscow.

Automated three‐dimensional georadar acquisition

SEG Technical Program Expanded Abstracts 1997, 1997
A self-tracking laser theodolite with automatic target recognition capabilities has been adapted to serve as a real-time positioning system for the acquisition of three-dimensional (3-D) georadar data. This surveying system provides complete coordinate information with high accuracy.

Analysis of georadar reflection responses

Proceedings of the 2nd International Workshop onAdvanced Ground Penetrating Radar, 2003., 2004
Understanding the nature of the georadar reflection response in terms of the dielectric permittivity and conductivity contrast is important in the realm of interpretation. This motivates the present study, which has the aim to carry out an experiment in a controlled fashion such that the relation can be established between the measurement and the ...

Preliminary Study of Roots by Georadar System

2020
This study has made it possible to draw up a state of the art of the GPR radar domain. This measuring instrument is used in many fields of application such as archeology, space exploration and even in civil engineering. Its non-destructiveness of the probed environment is its main advantage.

Inversion of guided waves in georadar data

Proceedings of the XIII Internarional Conference on Ground Penetrating Radar, 2010
We analyze the dispersive characteristics of the electromagnetic guided waves (at georadar frequency) to infer the electrical properties of materials that constitute a layered wave guide.
