Ground-Penetrating Radar Imaging Techniques Applied in 3d Environment: Example in Inactive Dunes

Abstract: ABSTRACT. The increased use of Ground-Penetrating Radar (GPR) in several areas of knowledge has introduced an impressive number of new methodological procedures, adapted from other areas, such as seismic reflection, or developed specifically for the GPR. A summary of the advances in acquisition, processing and interpretation of GPR data is presented in this paper. Some of the techniques were applied to a 3D GPR survey in a study area, whose substrate is composed by sedimentary sequences of paleodunes or inacti… Show more

“…As such, only large sections that may host the desired layer can be detected. According to Castro et al (2014), one of the technical limitations of GPR is the local physical characteristics, such as electromagnetic properties, because sandy soil layers containing high levels of clay, moisture and/or salinity compromise the prospection scope due to the fact that the electromagnetic wave energy is highly attenuated, which impedes diffusion to lower layers.…”

“…According to Castro et al (2014), the application of techniques for the acquisition, processing, and interpretation of GPR data acquired in two orthogonal directions illustrates the advantages of 3D surveys in the detection and imaging of buried targets and depositional features. Although there are currently no reports of the accuracy of Georadar technique for the adequate construction of dams, this technique is widely used for imaging alluvial areas (BOWLING et al, 2005;GAUW et al, 2006), which reinforces the possibility of using GPR in the sustainable water storage technology of arid and semiarid zones.…”

“…Um grande número de trabalhos utilizando o método geofísico de Georadar relacionado a sistemas eólicos já foi publicado: Silva et al, 2010, Rocha et al, 2013, Castro et al, 2015, Aranha et al, 2013 Entretanto, em metassedimentos eólicos esse método ainda não havia sido aplicado para identificar estruturas e correlacionar tipos litológicos.…”
