Ground penetrating radar (GPR) devices encompass various types designed for specific applications in underground sensing and imaging. One type is air-launched GPR, typically used for geological surveys, bedrock mapping, and buried object detection. This type of GPR is deployed from aircraft or drones to effectively cover large areas. Another type is vehicle-mounted GPR, which is used for road and bridge inspections, utility detection, and pavement analysis. These systems are integrated into vehicles to facilitate rapid data collection while traversing surfaces. Handheld GPR units are portable devices used for localized inspections, such as locating buried utilities, detecting voids or anomalies in structures, and archaeological investigations. These units are lightweight and maneuverable, making them suitable for applications requiring flexibility and accessibility.
A ground penetrating radar (GPR) device is a non-destructive geophysical tool used to detect and map subsurface features by emitting high-frequency electromagnetic pulses into the ground. These pulses penetrate the soil and are reflected when encountering changes in material properties, such as transitions between soil and buried objects or layers of different compositions. By analyzing the timing and strength of these reflections, GPR devices create detailed subsurface images that reveal the presence, depth and characteristics of buried objects, geological structures, archaeological artifacts and underground utilities. GPR technology is widely used in engineering, construction, environmental assessment, geology and forensic investigations due to its ability to provide real-time data without excavation or disruption to the site.
GPR tools encompass the full range of equipment and accessories used in ground penetrating radar applications. These tools include GPR control units or consoles, which transmit and receive radar signals, display data and manage system settings. Antennas or transducers are critical components that transmit radar pulses into the ground and capture the reflected signals. GPR tools also include data processing software to interpret radar data, generate subsurface images, and perform analysis. Accessories such as GPS receivers, rugged enclosures for field use, and specialized probes or accessories for specific applications are also part of GPR tools. These tools collectively enable precise and efficient subsurface imaging and investigation across various industries and disciplines.
