Many of these applications also fall into the category of engineering geophysics. A wide range of equipment can be rented from K. Jones Instruments. While there are differences of opinions and values often overlap, GPR antennas can be grouped into low, medium, and high frequencies.

Our Past, Present and Future: GPR Antennas
Ground Penetrating Radar GPR uses a high frequency radio signal that is transmitted into the ground and reflected signals are returned to the receiver and stored on digital media. The computer measures the time taken for a pulse to travel to and from the target which indicates its depth and location. The reflected signals are interpreted by the system and displayed on the unit's LCD panel. In order to find the location and depth of an object, buried subsurface, various types of GPR equipment are used to collect the data. The type of GPR equipment required is dependent on the depth and size of the target to be located.
Ground-penetrating radar GPR is a geophysical method that uses radar pulses to image the subsurface. GPR can have applications in a variety of media, including rock, soil, ice, fresh water, pavements and structures. In the right conditions, practitioners can use GPR to detect subsurface objects, changes in material properties, and voids and cracks. A GPR transmitter and antenna emits electromagnetic energy into the ground. When the energy encounters a buried object or a boundary between materials having different permittivities , it may be reflected or refracted or scattered back to the surface.
