The multifold acquisition principle was applied to a borehole radar survey, performed in a granitic site (Grimsel Test Site, Switzerland). Two multifold coverage acquisitions (40-fold and 20-fold) were carried out in a subhorizontal borehole. Instrum

The detection of millimeter-wide discontinuities such as fissures in subsurface geological formations may be possible by means of GPR soundings, but establishing a law for the electromagnetic wave propagation velocity from field data in order to inte

In order to understand various aspects of radar wave propagation, a survey of electromagnetic wave behaviour relative to the geological characteristics of the formations prospected was undertaken. The sites chosen for the tests were a granite quarry

Summary Standard approaches of ground-penetrating radar tomographies consist in computing velocity tomogram and attenuation tomogram from travel times and amplitudes extracted from electromagnetic signals in the time domain. The multi-frequency tomog

As in seismic surveys, forward modeling is essential to the geological interpretation of georadar data. Because a radar signal is broad band, modeling radar waves in a realistic medium requires knowing the frequency dependence of the effective dielec
