Abstract :
Guided electromagnetic wave pulses were excited on long, thin conducting wires in water-filled, uncased boreholes by a VHF monostatic borehole radar. Reverberations were recorded at the excitation point. Spectral warping focused the dispersed echoes in space-time. Echo patterns are correlated with geological and geotechnical structures, e.g. bedding plane intersections.
