GPR Method Overview
Ground Penetrating Radar (GPR) is non-destructive geophysical tool. It measures travel times and magnitudes of reflected pulses of EM radiation and then a 2-D or a 3-D subsurface model is generated.
Antennas with various frequencies (typically 200 MHz to 2.6 GHz) are used for different applications.
