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.

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 ...

Numerical modeling of borehole georadar data

GEOPHYSICS, 2002
High‐frequency electromagnetic (EM) wave propagation phenomena associated with borehole georadar experiments are complex. To improve our understanding of the governing physical processes, we present a finite‐difference solution of Maxwell's equations in cylindrical coordinates.

Einsatz des Georadars im Ingenieurbau

1990
Das GeoRadar, auch Bodenradar genannt, ist ein vollkommen zerstorungsfrei arbeitendes Mesverfahren der Geophysik. Dieses elektromagnetische Scanning funktioniert etwa so wie ein Echolot, nur das bei dem Echolot Schallwellen, beim GeoRadar aber elektromagnetische Wellen ausgesandt werden. Der Sender erzeugt kurze elektromagnetische Impulse.

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 ...
