In this contribution, some possible effects of large band electromagnetic interferences on Ground Penetrating Radar (GPR) data are shown, and a possible way to counteract them is shown, too. The mitigation of the interferences is implemented thanks to a prototypal reconfigurable stepped frequency GPR system, that allows to program the integration time of the harmonic tones vs. the frequency. In...

A comprehensive analysis of electromagnetic (EM) inversion applied to pavement profiling by using a monostatic ground penetrating radar (GPR) is presented. Since in GPR systems using transfers EM (TEM) horns, the antenna is positioned close to the the investigated medium and a strong EM interaction occurs. This effect is taken into account by modeling the antenna with equivalent sources placed ...

Ground-penetrating radar (GPR) technology finds applications in many areas such as geophysical prospecting, archaeology, civil engineering, environmental engineering, and defence applications as a non-invasive sensing tool [3], [6], [18]. One key component in any GPR system is the receiver/transmitter antenna. Desirable features for GPR antennas include efficient radiation of ultra-wideband pul...

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...

Ž . Swiss Federal Railways SBB inspect their railway tracks at regular intervals. The first step of track renewal planning is a geotechnical study. Inspection is focused on the thickness of the ballast, on subsoil material penetrating upwards into the ballast and on geotechnical properties of subgrade and subsoil materials. Up to now, the inspection has been done mainly by digging trenches at e...

We introduce a combination of high-dimensional analysis of variance (HANOVA) and sequential probability ratio test (SPRT) to detect buried objects from an array ground penetrating radar (GPR) surveying a region of interest in a progressive manner. Using HANOVA, we exploit the transient characteristic of GPR signals in the time domain to extract information about buried objects at xed positions ...

Ground Penetrating Radar (GPR) is a flexible and cost-effective tool for performing structural integrity assessment and quick damage evaluation of manmade structures, including cultural heritage (CH) assets. In this context, this paper deals with the usefulness of GPR surveys enhanced by the use of a Microwave Tomographic data processing approach as a methodology for the diagnosis and monitorin...

This paper provides a comparative study between microwave tomography and synthetic 14 time-reversal imaging techniques as applied to ground penetrating radar (GPR) surveys. The 15 comparison is carried out by processing experimental data collected at a controlled test site, with 16 various types of buried targets at given subsurface depths and representative soil conditions. It is 17 shown that...

Ground Penetrating Radar (GPR) is one of the most widely exploited diagnostics tools in the fields of the water monitoring and management as well as in the recent application fields of the agricultural geophysics. In this work, we present the most recent results concerning with a state of art data processing for GPR based on accurate models of the inverse scattering at the basis of the sensing ...

Geophysical methods are important tools for a wide range of geological, hydrogeological, and engineering investigations. Conventional processing techniques for electromagnetic tools often use approximations that may be either inappropriate or only provide limited resolution. Higher resolution images can be derived by using more sophisticated approaches that explicitly take into account the elec...
