[1] In this study, we evaluate the use of ground‐penetrating radar (GPR) to investigate the effects of bacterial activity in water saturated sand. A 90‐day laboratory‐scale controlled experiment was conducted in a flow‐through polycarbonate sandbox using groundwater from the Kansas River alluvial aquifer as inoculum. After 40 days of collecting baseline data, bacterial growth was stimulated in ...

Ground-penetrating radar mapping allows for a three-dimensional analysis of archaeological features within the context of landscape studies. The method’s ability to measure the intensity of radar reflections from as deep as 5 meters in the ground can produce images and maps of buried features not visible on the surface. A study was conducted in the desert of the American Southwest to study the ...

The use of ground penetrating radar (GPR) for detecting the presence of near-surface interfaces is a scenario of special interest to the underground coal mining industry. The problem is difficult to solve in practice because the radar echo from the near-surface interface is often dominated by unwanted components such as antenna crosstalk and ringing, ground-bounce effects, clutter, and severe a...

The objectives of our study were to assess the feasibility of using ground-penetrating radar (GPR) to study roots over a broad range of soil conditions in the southeastern United States. Study sites were located in the Southern Piedmont, Carolina Sandhills and Atlantic Coast Flatwoods. At each site, we tested for selection of the appropriate antenna (400 MHz versus 1.5 GHz), determined the abil...

Abstract This paper presents a review on Ground Penetrating Radar (GPR) detection and mapping of buried utilities which have been widely used as non-destructive investigation efficiently in terms usage. The reviews cover experimental design GPR data collection survey, pre-processing, extracting hyperbolic feature using image processing machine learning techniques. Some the issues challenges fac...

ENSCO, Inc. is investigating a novel approach to data fusion of magnetic and ground-penetrating radar (GPR) data to characterize previously detected buried targets. The method exploits a single model of the subsurface to predict both magnetic and GPR data observations. By determining the best single model that constrains both data sets, the optimum identification is computed. Using an a priori ...

As Ground Penetrating Radar (GPR) is increasingly employed for assessing the condition of bridge decks, quantifying and controlling the quality of GPR data becomes an important challenge. This paper uses a methodology to assess the accuracy of deck condition measures, and demonstrates the methodology in a case study involving real data. The latter are generated during GPR applications on a larg...

Introduction: The thickness of the lunar regolith and potential for frozen water are important considerations for future lunar outposts. However, the thickness of the regolith is largely unknown and the presence of water ice has yet to be directly detected at or beneath the surface. A rapid and economical geophysical method to determine both the thickness of the lunar regolith and possibly iden...

Ground Penetrating Radar (GPR) has proved to be a successful technique for the detection of landmines and Improvised Explosive Devices (IEDs) buried in ground. In last years, novel architectures safe fast detection, such as those based on GPR systems onboard Unmanned Aerial Vehicles (UAVs), have been proposed. Furthermore, improvements hardware signal processing techniques resulted more efficie...
