Ground Penetrating Radar (GPR) is a non-destructive geophysical method that involves the utilization of electromagnetic pulses transmitted into the ground. Those pulses are reflected at interfaces within the subsurface and captured by specialized receivers at the surface. Such interfaces may be soil or rock layers, groundwater table or artificially made objects located underground.
GPR measures the electromagnetic properties including the magnetic permeability, dielectric permittivity and electrical conductivity and its ultimate purpose is to create a detailed mapping of the subsurface. It’s mostly used in small scale engineering projects and provides high resolution subsurface profiles.
