Ground Penetrating Radar (GPR) is a Non-Destructive Testing (NDT) method in near-surface ground investigations. The GPR uses high-frequency-pulsed electromagnetic waves (10 to 3000 MHz) to acquire subsurface information. The electromagnetic(EM) wave is radiated from a transmitting antenna, travels through the sub-surface. If the wave hits a buried object that has different electrical properties from the surrounding medium/soil, then part of the energy/EM wave shall “reflect” back to the surface, while part of its energy continues to travel downward. The wave that is reflected back to the surface is captured by a receive antenna, and recorded on a digital storage device for later interpretation.
