Numerical modelling of Ground Penetrating Radar

The use of ground penetrating radar (GPR) is growing rapidly, especially for shallow depth exploration problems. Its inherent high resolution and non-destructive nature are GPR's main advantages over other geophysical methods. The diversity of the areas which GPR has been employed ranges from the ice thickness probing at the poles (Bishop et al.,1980) to the investigation for buried antiquities (Giannopoulos et al.,1993). However, GPR is most commonly employed for the location of buried utility plans for which it has been proved to be very effective (Annan et al.,1984). A review of the method, its applications and limitations can be found in an IEE special issue on GPR (Daniels et al.,1988).
