3D_GPR_URBAN

Author: Van Schoor, Michael Date: Oct 2021 The versatility of ground penetrating radar (GPR) to solving different subsurface detection problems in urban settings is demonstrated. In particular, the advantage of the 3D approach to GPR surveying and how it complements the traditional ... Read more
Airborne ground penetrating radar: practical field experiments

Author: Van Schoor, Michael ; Vogt, D Date: Oct 2013 The performance of ground penetrating radar (GPR) under conditions where the ground coupling of the antenna is potentially compromised is investigated. Of particular interest is the effect of increasing the distance between the antennae and ... Read more
A comparison of GPR performance at various frequencies - a guide to improved survey design

Author: Kgarume, Thabang E ; Brovko, Fatheela ; Van Schoor, Michael Date: Sep 2015 This paper aims to demonstrate, through practical examples and numerical modelling, the trade-off between range and resolution in ground penetrating radar (GPR) prospecting. GPR surveys can easily fail when the target and host rock properties ... Read more
A controlled monitoring study of simulated clandestine graves using 3D ground penetrating radar

Author: Van Schoor, Michael ; Nienaber, WC ; Marais-Werner, A Date: Jun 2017 A controlled three-dimensional ground penetrating radar monitoring study over simulated clandestine graves was conducted near Pretoria, South Africa, in which the detectability of graves as a function of post-burial interval was assessed, as ...

Delineation of rockburst fractures with ground penetrating radar in the Witwatersrand Basin, South Africa

Author: Grodner, M Date: Sep 2001 The depth of mining in the gold mines of the Witwatersrand Basin, South Africa is continuously increasing, with several mines already stopping at depths exceeding 3500m. Due to the high stresses imposed on the rock mass in these deep level ... Read more
Identifying structural damage with ground penetrating radar

Author: Van Schoor, Michael ; Fourie, CJS Date: Jul 2008 Ground penetrating radar (GPR) and electrical resistance tomography (ERT) surveys were conducted in an urban environment in an attempt to identify the cause of severe structural damage to a historically significant residential property in ...

Integration of in-mine seismic and GPR surveys to gain advanced knowledge of Bushveld Complex orebodies

Author: Onyebueke, EO ; Manzi, MSD ; Rapetsoa, MK ; Kgarume, Thabang E ; Westgate, M ; Durrheim, RJ ; Pienaar, M ; Sihoyiya, M ; Mpofu, Mvikel ; Van Schoor, Abraham M Date: Aug 2023 Improving the exploration of deep-seated mineral deposits and assessing the stability of the mine pillars require that geophysical techniques are deployed in a fast and cost-effective manner with minimal environmental impact. This research ... Read more
Investigating airborne low frequency GPR antenna-ground coupling through modelling

Author: Vogt, D ; Van Schoor, Michael Date: Oct 2013 Ground Penetrating Radar (GPR) is often a good tool for detecting near surface structure, as it is cheap, fast and has high resolution. At lower frequencies, it is an excellent tool for detecting voids such as sinkholes, old excavations or ... Read more
LiDAR-based 3D mapping and localisation system for Ground Penetrating Radar

Author: Ogunniyi, Samuel O ; Withey, Daniel J ; Marais, Stephen T ; Crafford, Gerhardus J Date: Jan 2020 As mining activities expand into deeper mines in South Africa's geology there are increasing safety concerns for personnel working within these mines. Ground Penetrating Radar can be used to find faults in the rock face; however, current GPR ... Read more
Tree root mapping with ground penetrating radar

Author: Van Schoor, Michael ; Colvin, C Date: Sep 2009 In this paper, the application of ground penetrating radar (GPR) for the mapping of near surface tree roots is demonstrated. GPR enables tree roots to be mapped in a non-destructive and cost-effective manner and is therefore a useful prospecting ... Read more
