Root system architecture (RSA) refers to the geometric features and topology of root system. Ground-penetrating radar (GPR) is a possible method RSA reconstruction. However, because not directly accessible by GPR, GPR-based reconstruction must be complemented manual connection points, resulting in limited accuracy. In this study, we used both GPR direct excavation obtain 3D coordinates (XYZ coo...

During the last decade Ground Penetrating Radar (GPR) has proved its ability to act as a powerful geophysical tool for subsurface investigations. GPR is a more user friendly and cost-effective tool due to recent technological developments. Lower cost and simple operation has increased the practice of GPR in the utility locating market as well as other traditional markets. Deploying GPR methods ...

We are interested in Ground Penetrating Radar (GPR) as a geophysical tool useful for determining the depth of the ground water table (GWT) and for monitoring shallow water infiltration in sandy soils. At hydrostatic equilibrium, the water content distribution in a homogeneous unsaturated soil down to the water saturated zone depends on the soil water retention function. A classical way to fit r...

Introduction: In the frame of the NetLander mission, the Centre d’étude des Environnements Terrestre et Planétaires (CETP) has developed an impulse ground penetrating radar (GPR) operating at very low central frequencies from 2 to 6 MHz [1]. This instrument, named TAPIR (Terrestrial And Planetary Investigation Radar), aims at exploring the geological features in the deep Martian subsurface and ...

Abstract. Seasonal snowpack deeply influences the distribution of meltwater among watercourses and groundwater. During rain-on-snow (ROS) events, structure properties different snow ice layers dictate quantity timing water flowing out snowpack, increasing risk flooding jams. With ongoing climate change, a better understanding processes internal influencing outflows is needed to predict hydrolog...

Integrated remote sensing and geophysical methods can provide detailed information about buried cultural heritage. We implemented an integrated survey protocol (IREGA, Integrated REmote-sensing and Geophysical prospecting for Archaeology) and tested the performance of the method in the area of the ancient Roman town of Aquileia, NE Italy, to define and characterize microareas of archaeological ...

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...

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...

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,...

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...
