DETERMINATION OF THE GROUND-WATER LEVEL BY MODERN NON-DISTRUCTIVE METHODS (GPR TECHNOLOGY) [PDF]

open access: yesAerul şi Apa: Componente ale Mediului, 2011
Determination of the ground-water level by modern non-dis¬tructive methods (ground-penetrating radar technology). Ground Penetrating Radar (GPR) is now a well-accepted geophysical technique, which unfortunately in our country its less used. Historically,

GPR Imaging for Deeply Buried Objects: A Comparative Study Based on Compositing of Scanning Frequencies and a Chirp Excitation Function

open access: yesGeosciences, 2019
Compositing of ground penetrating radar (GPR) scans of differing frequencies have been found to produce cleaner images at depth using the Gaussian mixture model (GMM) feature of the expectation-maximization (EM) algorithm.

A Multiple Migration and Stacking Algorithm Designed for Land Mine Detection [PDF]

open access: yes, 2014
This paper describes a modification to a standard migration algorithm for land mine detection with a ground-penetrating radar (GPR) system. High directivity from the antenna requires a significantly large aperture in relation to the operating wavelength,

Influence of grain size, shape and compaction on georadar waves: example of an Aeolian dune

open access: yes, 2012
Many Ground Penetrating Radar (GPR) profiles acquired in dry aeolian environment have shown good reflectivity inside present-day dunes. We show that the origin of this reflectivity is related to changes in grain size distribution, packing and/or grain ...
