6 Frequently Asked Questions about Ground Penetration Radar (GPR)

by admin in Uncategorized

Ground–penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. This nondestructive method uses electromagnetic radiation in the microwave band and detects the reflected signals from subsurface structures. And because this technology is relatively new, its first use was in the late 1950s, there may be some confusion about the […]

Ground Penetrating Radar

by admin in Blog

GPR operates by sending short pulses of electromagnetic radiation (in the approximate frequency range for an FM radio) into a material and recording the strength and the time required for the return of the reflected signal. Reflections are produced whenever the energy pulse encounters a material with different dielectric (electrical) properties. Reflecting interfaces may be […]

How GPR Works

by admin in Blog

How Deep Can It Go? This is probably one of the most commonly asked questions. In most cases, an estimated depth range can be determined with accuracy based upon the subsurface material and the frequency of the GPR antenna. For applications requiring higher resolution, such as locating rebar or conduits in concrete, a higher frequency […]
