Ground Penetrating Radar (GPR) and airborne thermography have been used for the location of buried spring barrier ponds and for the investigation of the shallow subsoil. Thermography has been selected for its ability to cover a wide area in a short time, the GPR has been chosen for the ability to distinguish, in great detail the presence of permeable layers composing the subsoil. Very positive ...

Radar imaging from unmanned aerial vehicles (UAVs) is a dynamic research topic attracting huge interest due to its practical fallouts. In this context, article provides comprehensive review of the current state art and challenges related UAV-based ground-penetrating radar (GPR) systems. First, description available prototypes provided in terms technology, UAV platforms, navigation control devic...

It is necessary to detect the target reflections in ground penetrating radar (GPR) images, so that surface metal targets can be identified successfully. In order to accurately locate buried metal objects, a novel method called the Multiresolution Monogenic Signal Analysis (MMSA) system is applied in ground penetrating radar (GPR) images. This process includes four steps. First the image is deco...

A simulated clandestine shallow grave was created within a heterogeneous, made-ground, urban environment where a clothed, plastic resin, human skeleton, animal products, and physiological saline were placed in anatomically correct positions and re-covered to ground level. A series of repeat (time-lapse), near-surface geophysical surveys were undertaken: (1) prior to burial (to act as control), ...

This paper reports the results of a ground penetrating radar (GPR) survey ground-floor Academia Gallery (Florence, Italy) where Michelangelo’s David is exhibited to public. The equipment used was step-frequency GPR operating in 100 MHz-1 GHz band, named ORFEUS. covered an area 13 m × 7.3 m, and scans were performed along two orthogonal directions. Acquisitions same direction separated by 0.25 f...

This paper is a review of published studies involving the use ground penetrating radar (GPR) on wood structures. It also contains background information to help reader understand how GPR functions. The structures began grow in popularity at turn millennium. has many characteristics that make it attractive as an inspection tool for wood: faster than acoustic and stress wave techniques; does not ...

[1] The surface pattern of vegetation influences the composition and humification of peat laid down during the development of a bog, producing a subsurface hydrological structure that is expected to affect both the rate and pattern of water flow. Subsurface peat structures are routinely derived from the inspection of peat cores. However, logistical limits on the number of cores that can be coll...

Ground penetrating radar (GPR) has been applied for ballast layer inspection two decades, mainly the analysis of fouling levels. However, some issues that affect quality remain unsolved, such as involving GPR equipment (antenna) and correlation between indicator index. With aim solving these issues, in this paper, we investigated difference results different antennas, data processing technique,...

This thesis is concerned with detection logarithms of non-metallic anti-personnel (AP) land mines and the related signal processing using stepped-frequency ground penetrating radar (SF-GPR) technique. Modern land mines are essentially made out of plastic and ceramic materials. This makes their detection using GPR sensor almost impossible without proper signal processing. Many signal processing ...

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...
