Ground Penetrating Radar (GPR) is a geophysical method that uses antennas to transmit and receive high-frequency electromagnetic waves to detect the properties and distribution patterns of materials inside a medium. Ground penetrating radar has various names in its early days, such as Ground probing Radar, Sub surface Radar, Geo Radar, Impulse Radar, Surface Penetrating Radar, etc., all of which refer to an electromagnetic wave method that uses high-frequency pulse electromagnetic waves to detect the internal structure of geological exploration targets.
