Ground Penetrating Radar

Ground Penetrating Radar (GPR) is used as an sub-surface imaging tool in a similar manner to airborne radar. Short pulses of electromagnetic energy are fired into the ground and reflect off the buried features. These reflections are recorded and a image of the sub-surface environment is developed as the radar is moved across the ground. The Applied & Environmental Geophysics group have applied this technique to a wide range of applications including pro-glacial sediment mapping, site characterisation, void location and archaeological studies.
Research centres on the development of processing and modelling techniques for improved interpretations, especially in the complex near-surface environment. Three-dimensional finite-difference time domain modelling techniques are used to simulate GPR wave propagation and provide synthetic radar sections for comparison with the observed data.
