Radar Tomography

This method consists of the use of a specialized set of borehole antennae in adjacent boreholes, one transmitter and one receiver. This technique can be employed to obtain a 2-D section showing the changes in the electromagnetic propagation speed between two boreholes using the same software as for seismic tomography. The technique is very efficient and has an exceptional resolution.


  • Trace stratigraphic changes between boreholes
  • Identify faults and shear zones in bedrock
  • Identify presence of voids in karst formations
  • Porosity / saturation estimates of geological formations or earth dams
