The finite-difference time-domain (FDTD) method is used to simulate three-dimensional (3-D) geometries of realistic ground-penetrating radar (GPR) scenarios. The radar unit is modeled with two transmitters and a receiver in order to cancel the direct signals emitted by the two transmitters at the receiver. The transmitting and receiving antennas are allowed to have arbitrary polarizations. Sing...

Landmine problem is enormous and worldwide. Impulse ground penetrating radar (ImGPR) is one of the technologies that have been extensively researched as a means of improving landmine detection efficiency. We propose two methods to detect buried landmines. Both methods are based on background subtraction techniques to detect buried plastic landmines. The first method uses adaptive background est...

Ground penetrating radar (GPR) has gained a distinguished place during recent years as a tool for investigating subsurface objects, yet its output is of low resolution, and in need of further processing in order to make its output readily interpretable. Furthermore, GPR data collected in a typical survey is usually in large quantities, and dealing with such quantities manually to produce final ...

This paper describes the development of new air-coupled ultrawideband ground-penetrating radar (GPR) for highway pavement and bridge deck inspections that can achieve high spatial resolution and high inspection performance while operating on vehicles driving at regular highway speeds. Themajor design features include dual-frequency band operation, 8 gigasamples per second high-speed real-time d...

This paper describes the activities of the Demining Technologies (DeTec) team from the École Polytechnique Fédérale de Lausanne (EPFL), and personnel of Brooks Enterprises International, Inc., Huntsville, Al, USA, while testing the prototype DeTec-2 Ground Penetrating Radar (GPR) in Cambodia. The team, under the direction of Prof. J. D. Nicoud, tested the prototype radar from 18-21 November 199...

We study the capabilities of low frequency radar systems to sound the subsurface in arid countries. This approach is based on the coupling between two complementary radar techniques: the airborne Synthetic Aperture Radar (SAR) used in L-band (1.2 GHz) for imaging large scale subsurface structures, and the Ground-Penetrating Radar (GPR) used between 500 and 900 MHz for sounding soils at a local ...

[1] Ground-penetrating radar (GPR) helps to constrain the origin of relict and largely buried fluvial channels in the Bir Kiseiba region of southern Egypt. Our results indicate that the trunk channel to a tributary system identified in Shuttle Imaging Radar data is incised 10–12 m into bedrock, was southwest draining in its final configuration and laterally migrating toward the northwest, and a...

Landmines are affecting the lives and livelihood of millions of people around the world. The video impulse ground penetrating radar system for detection for small and shallow buried objects has been developed. The hardware combines commercially available components with components specially developed or modified for being used in the system. The GPR system has been desired to measure accurately...

Ground Penetrating Radar is becoming increasingly popular to use as a non-destructive assessment method for investigating reinforced concrete structures. The large amount of data collected take significant level of experience to interpret. Ground Penetrating Radar scans of concrete produce images which are made of arc segments. The shape of each arc is determined by the shape of the object, pos...
