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 ...

-Field experience has shown that soil conditions can have large effects on Ground Penetrating Radar (GPR) detection of landmines. We discuss available models for the prediction of the dielectric constant from soil physical properties including bulk density, soil texture, and water content. The soil dielectric constant determines the attenuation of the radar signal. The contrast between the diel...

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...

Quantifying the benefit of airborne and ground sensor fusion for target detection Report Title In this paper, a study involving the detection of buried objects by fusing airborne Multi-Spectral Imagery (MSI) and ground-based Ground Penetrating Radar (GPR) data is investigated. The benefit of using the airborne sensor to cue the GPR, which will then search the area indicated by the MSI, is inves...

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...

ground penetrating radar (gpr) method as a high resolution non-destructive geophysical method is used for detection of shallow subsurface targets. this method is based on the transmission of electromagnetic waves inside the earth and recording the reflected waves from the subsurface. as the method uses high-frequency electromagnetic waves in the frequency ranges of 12.5 to 2500 mhz (called gpr ...
