The VIY-2 Ground Penetrating Radar
Abstract The VIY-2 ground penetrating radar (GPR) with unique sounding possibilities and use simplicity is presented at this paper. The VIY-2 GPR combines all units (synchronizer, transmitting and receiving modules, power supply and antenna system) into single case. The VIY-2 GPR communicates with computer via standard interface RS232 or USB 1.0. Utilized by the VIY-2 GPR technical solutions ...

Topographic Correction of GPR Profile Based on Odometer and Inclinometer Data
Abstract— Usually, data obtained by ground penetrating radar (GPR) are displayed as a rectangular 2D picture (profile), vertical and horizontal axes of which are proportional to depth and traveled distance, respectively. Surface, generally, is not horizontal, that leads to distorted view of irregularities in the GPR profile. To eliminate these distortions a topographic correction is used. ...

Mapping of Potential void features using ground penetrating radar case study
Mayo Clinic - Jacksonville, Florida GeoView conducted a ground penetrating radar (GPR) study in 2009 at the Mayo Clinic in Jacksonville, Florida. The GPR study was designed to locate anomalous features potentially associated with shallow voids between a recently installed terrazzo floor and the underlying concrete. The GPR data was collected with a GSSI SIR 3000 using a 2600 Megahertz antenna. ...

Forensic applications including mapping and classification of tsunami sand deposits and sand dunes with ground penetrating radar
The coastal region experiences erosional, transportational and depositional events during mega events such as tsunami. The onshore deposits are significant in determining the past events of high–energy events in the coastal region. The Optically Simulated Luminescence (OSL) dating of the sediments by combining Ground Penetrating Radar (GPR) records will reveal the past tsunami events. OSL dates ...

Ground Penetrating Radar for mining
Ground-penetrating radar (GPR) is a well-established technology that has earned its place as the go-to technology for many subsurface imaging applications. No other geophysical method comes close to GPR's ease of deployment, nor the amount of ground that an operator can cover in a typical day. Workers can quickly and efficiently collect quality high-resolution data, which often facilitates ...

GPR goes underground: Pipe Penetrating Radar
Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR) either robotically or by manned entry to reveal wall thickness, delamination, voids, and other conditions that enable more precise determination of pipeline integrity and verifications for trenchless technology rehabilitation. PPR, when applied to pipe-bursting applications, can be ...
