Testing of a georadar in tunnel drifting
5th EEGS-ES Meeting, 1999The 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.

Analysis of georadar reflection responses
Proceedings of the 2nd International Workshop onAdvanced Ground Penetrating Radar, 2003., 2004Understanding 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 ...
