GPR > Field Examples

The surface Ground Penetrating Radar (GPR) method is comparable to the reflection seismic method. The source array is an antenna generating a very high-frequency electromagnetic pulse. The range of central frequencies used is very wide. It varies from a few tens of MHz to GHz. Electromagnetic waves propagated in the formation are recorded by a receiving antenna. The distance between the source and the receiver antennas varies from a few centimeters to several meters.

Figures show different GPR devices:

  • SIR300 (GSSI) Radar system with a 400 MHz antenna
  • RIS 0 (IDS) Radar system with a set of antennas: 200, 600 and 90 MHz
  • Ground penetrating radar survey of an archaeological site in Jordan
