Keeping track of underground utilities through maps or real physical signs is essential for their maintenance and quick repairs, whenever required, without causing much obstruction to day to day life. It is not uncommon that maps are misplaced or real physical signs are destroyed. In such situations, digging and excavation becomes unavoidable during repair works. Ground penetrating radar (GPR) ...

[1] Full‐resolution 3D Ground‐Penetrating Radar (GPR) data were combined with high‐resolution hydraulic conductivity (K) data from vertical Direct‐Push (DP) pro f i l e s to cha rac te r i ze a por t i on of the h igh ly heterogeneous MAcro Dispersion Experiment (MADE) site. This is an important first step to better understand the influence of aquifer heterogeneities on observed anomalous trans...

This paper reports the results of integrated geophysical surveys performed inside Monastery St Chiara in Nardó southern Italy. Ground-penetrating radar (GPR) and electrical resistivity tomography (ERT) investigations were carried out to find tomb Sister D’Amato, whose location has been lost over centuries. Isabella D'Amato was a charismatic holy figure. She died 1693. buried monastery but her b...

This paper proposes a probabilistic conic mixture model based on a classification expectation maximization algorithm and applies this algorithm to Ground Penetrating Radar (GPR) spatial data interpretation. Previous work tackling this problem using Hough transform or neural networks for identifying GPR hyperbolae are unsuitable for on-site applications owing to their computational demands and t...

Ground Penetrating Radar (GPR) has been used recently for diagnostics of the railway infrastructure, particularly ballast layer. To overcome fouling, mechanized cleaning process, which increases track occupancy time and cost, is usually used. Hence it crucial significance to identify at stage life cycle, level should be initiated. In present study, a series in situ GPR surveys on selected secti...

A 30 m by 30 m two-dimensional grid was designed on a flat bench behind a quarry face of predominantly limestone with thin shale layers located at a Bonner Springs, Kansas site to test the utility of ground-penetrating radar (GPR) for stratigraphic studies. GPR data were collected along seven lines parallel to the quarry face and seven lines perpendicular to the quarry face, each separated by 5...

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...

Ground penetrating radar (GPR) has been widely used in geologic, hydrogeologic, and civil engineering purposes. Correlated with geological exposures and trenches, GPR data can offer detail subsurface information to past earthquakes investigation. McClymont et al. [2][3] show very good performance of GPR for fault characterization. In this paper, we show an example of practical application of GP...

The versatility of the three-dimensional (3–D) finitedifference time-domain (FDTD) method to model arbitrarily inhomogeneous geometries is exploited to simulate realistic groundpenetrating radar (GPR) scenarios for the purpose of assisting the subsequent designs of high-performance GPR hardware and software. The buried targets are modeled by conducting and dielectric prisms and disks. The groun...

In this paper we consider the development of algorithms for the automatic detection of buried threats using ground penetrating radar (GPR) measurements. GPR is one of the most studied and successful modalities for automatic buried threat detection (BTD), and a large variety of BTD algorithms have been proposed for it. Despite this, large-scale comparisons of GPR-based BTD algorithms are rare in...
