Ground Penetrating Radar (GPR)

Ground Penetrating Radar (GPR) is a geophysical imaging technique used for subsurface exploration and monitoring. It is widely used within the forensic, engineering, geological, mining and archeological communities. Since recent hardware and software advances, real time cursory analysis can be performed at the site.

GPR emits a short pulse of electromagnetic energy, which is radiated into the subsurface. When this pulse strikes an interface between layers of materials with different electrical properties, part of the wave reflects back, and the remaining energy continues to the next layer. Gehrig, Inc. utilizes the newest software and hardware technologies offered by the leading GPR manufacturer in the world. GPR datasets can be collected in 1D, 2D or 3D formats.
