Both the transmitter and receiver are types of antennas, and they utilize different frequencies depending on the desired depth of investigation and the type of material being scanned. The control unit, or interface through which the operator runs the device, then interprets the echoes with the help of software and mapping tools.Īntennas play a crucial role in GPR's subsurface penetration. The transmitter sends electromagnetic signals into the subsurface, creating echoes that the receiver (normally the larger section that rolls along the ground) then detects. GPR systems consist of several essential components, including a transmitter, receiver, and control unit. While the appearance of different models may vary, the typical GPR unit looks like a push-mower with a digital screen attached to the handle. Understanding GPR technology and equipment Government entities have also discussed the value of using GPR to detect illegal objects at nuclear facilities and enhance subterranean physical protection systems. Military personnel use GPR to detect potentially deadly explosives such as undetonated mines, allowing them to dismantle them before they are disturbed and cause harm. In Italy, the technology was used successfully to locate the body of a suspected murder victim hidden in an underground cave. GPR also has applications in law enforcement for finding forensic evidence beneath the surface, from human bodies to buried illegal drugs or weapons. GPR was used successfully to detect lead contamination from battery disposal in Indonesia. For instance, archeologists used GPR to find the remains of the Württemberg-Stambol Gate in Belgrade, Serbia, preventing a construction crew from destroying an archeological site.Įnvironmental scientists use GPR to evaluate the impact of waste on the environment - for example, to see how far contamination from a landfill has spread or find buried waste material that needs to be removed. In archaeology, GPR can detect long-buried evidence of past civilizations, including buried structures, underground tunnels, military equipment, and human remains. For example, GPR was used to analyze water and landslide risk after a mine closed in Brazil, and to determine the probability of future disasters after a 2010 landslide in Poland. This application is useful for surveying potential construction sites, finding fresh groundwater sources, and assessing the risk of future landslides. Geologists can use GPR to determine soil properties and identify types of minerals found under the surface. For example, GPR was used to detect the location of a stormwater sewer beneath an existing metropolitan area, allowing for the safe installation of fiber lines with minimal digging. In construction, GPR is used for locating utilities, assessing concrete structures, and identifying potential hazards before excavation. GPR finds applications in a wide range of industries, making it a versatile tool for subsurface exploration. For example, a PVC pipe will have a different electromagnetic profile than a copper wire, and the technology can distinguish between those without the need to dig. GPR software can interpret that data to create a map of what is underground. Then, the reflecting pulse returns to the GPR receiver, which reads the signal distortions, displaying contrasts between objects below the surface along with depth information. The waves pass through objects under the surface and are distorted by conductive and dielectric properties. First, the transmitter sends high-frequency radio waves (between 10 MHz and 2.6 GHz) into the ground.

"For an expensive project, it's worth it to go ahead and do a scan before you break ground." Sean McConnel, geophysical archeologist at Bigman Geophysical and a recent guest on 4M's Everything Analytics Podcast. "Relative to the liability of a utility strike, the cost of a GPR scan is negligible," says Dr. GPR is useful for locating utilities because it detects what's beneath the surface without the expense and risk of digging or potholing. Ground Penetrating Radar (GPR) is a powerful subsurface exploration tool that uses electromagnetic waves to detect and map objects and structures beneath the ground's surface.
