Time-Lapse Ground Penetrating Radar (GPR) was employed to study used engine oil (UEO) contamination of sandy environment in laboratory setting. GPR is a near-surface geophysical methods that uses electromagnetic fields provide image the dielectric properties earth materials detect structures and changes within subsurface. This research aimed detect, monitor map migration UEO contaminant sand. T...

Research has focused on the development of a new integrated approach including ground penetrating radar (GPR) design, GPR signal forward modelling, and GPR signal inversion to estimate the dielectric permittivity and electric conductivity of the shallow subsurface. We propose to use an ultrawide band (UWB) stepped frequency continuous wave (SFCW) radar combined with an offground monostatic tran...

Ground-penetrating radar (GPR) crosshole tomography is widely applied to subsurface media images. However, the inadequacies of ray methods may limit resolution images, since method a type high-frequency approximation. To solve this problem, full waveform introduced for GPR inversion. inversion computationally expensive. In paper, we introduce trained neural network that can be evaluated very qu...

While there has been much interest in developing ground-penetrating radar (GPR) technology for rover-based planetary exploration, relatively little work has been done on the data collection process. Starting from the manual method, we fully automate GPR data collection using only sensors typically found on a rover. Further, we produce two novel data products: (1) a three-dimensional, photoreali...

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...

Radar remote sensing techniques are becoming more widely applied in dryland regions, because the lower frequency Synthetic Aperture Radar (SAR) systems enable significant penetration into the subsurface under very dry conditions, allowing subsurface characteristics to be interpreted. Field experiments at two contrasting sites in the Libyan Fazzān show ground-penetrating radar (GPR) can be used ...

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...

An automatic landmine detection algorithm using Ground Penetrating Radar is described. The algorithm combines outputs of multiple detection and feature extraction algorithms to generate a single confidence that a landmine is present at a location. The combination is performed using a fuzzy inference system. Results are provided for real data obtained in real-time with the Geo-Centers Vehicle Mo...

Multi-static ground-penetrating radar (GPR) uses an array of antennas to conduct a number of bistatic operations simultaneously. The multi-static GPR is used to obtain more information on the target of interest using angular diversity. An entirely computer controlled, multi-static GPR consisting of a linear array of six resistively-loaded vee dipoles (RVDs), a network analyzer, and a microwave ...
