Ground penetrating Radar (GPR) is an interesting device that can allow a non-destructive auscultation of the underground without any excavation. It is based on the use of high frequency electromagnetic waves, including reflection or diffraction that allows the detection of buried objects. In this work, we studied the possibility of using GPR for detecting of human targets under the rubble cause...

GPR (Ground Penetrating Radar) is one of subsurface sensing technologies, which has been used intensively since 1980s. Due to rapid development of both hardware and software, its possibilities have been considerably extended resulting in widening the area of its applications. While such applications as to detection of buried pipes and cables, archaeology and geology are established category, ne...

We tested an off-ground ground-penetrating radar (GPR) system at a fixed location over a bare agricultural field to monitor the soil freeze-thaw cycles over a snow-covered surface. The GPR system consisted of a monostatic horn antenna combined with a vector network analyzer, providing an ultra-wideband stepped-frequency continuous-wave radar. An antenna calibration experiment was performed to f...

In this paper, a signal processing technique is developed to reduce clutter due to ground bounce in ground penetrating radar (GPR) measurements. This technique is especially useful when a GPR is used to detect subsurface antipersonnel mines. The GPR clutter is modeled using a simple parametric model. Buried mine and clutter contributions are separated through a pair of coupled iterative procedu...

Ground penetrating radar (GPR) is a nondestructive sensor technology for detecting underground objects. GPR requires large-aperture antennas to survey a remote location precisely because of the expansion of microwaves. We propose a laser-driven GPR (LGPR) that uses microwave radiation from a laser plasma to achieve remote sensing. LGPR is expected to provide good spatial resolution with a small...

This paper addresses the problem of leakage in water distribution systems through the use of ground penetrating radar (GPR) as a nondestructive method. Laboratory tests are performed to extract features of water leakage from the obtained GPR images. Moreover, a test in a real-world urban system under real conditions is performed. Feature extraction is performed by interpreting GPR images with t...

We are very pleased to present the Special Issue “Recent Progress in Electromagnetic Theory and its Applications”, an outcome of the COST (European Cooperation in Science and Technology) Action TU1208 “Civil engineering applications of Ground Penetrating Radar”. The Special Issue comprises two parts: Part I includes eight papers on Ground Penetrating Radar (GPR) technology, methodology and appl...

Ž . This paper describes a newly developed stepped-frequency ground penetrating radar SFGPR prototype operating across the 10–620 MHz frequency band. The SFGPR system has been developed to improve the maximum penetration depth Ž . capability of ground penetrating radar GPR applications without degradation of resolving power. The radar has the unique capability to employ a short gate at each fre...

Ground penetrating radar (GPR) is a widely used sensor for land mine detection. However, GPR signal return is very susceptible to ground bounce and reflection of clutter objects, which makes the detection a difficult problem to date. In this paper, we propose to utilize two-sided linear prediction (LP) to model the background interference and then employ the residue energy to generate the test ...
