  • Introduction to Ground Penetrating Radar (GPR)

    About GPR Ground Penetrating Radar (GPR) is a non-invasive method of material analysis based on transmitting an ultra wide band EM signal into the materials. A part of the EM wave is reflected when it reaches a boundary between two materials with different electrical properties. The reflected signal gets recorded at the source of the EM wave and is displayed for the operator and ...

  • Mapping of Potential void features using ground penetrating radar case study

    Mayo Clinic - Jacksonville, Florida GeoView conducted a ground penetrating radar (GPR) study in 2009 at the Mayo Clinic in Jacksonville, Florida. The GPR study was designed to locate anomalous features potentially associated with shallow voids between a recently installed terrazzo floor and the underlying concrete. The GPR data was collected with a GSSI SIR 3000 using a 2600 Megahertz ...

  • Seismic reflection, seismic crosshole and ground penetrating radar case study

    Geophysical Investigation of the Crosstown Expressway. Tampa, FL In April, 2004 Pier 97 which supported an elevated roadway in Tampa, FL was vertically displaced (collapsed) approximately 10 feet (ft). At the time of the collapse it was not known whether the collapse was associated with geological conditions at the site, specifically karst conditions, or whether is was associated with a ...

  • Archaeological survey 2

    The site of the Meadows’ Wesleyan Cemetery in the Adelaide is thought to contain more than 130 unmarked graves. This site initially had a chapel constructed on it in 1840 and the first burial in 1855.  The initial chapel was replaced by a more substantial stone building in 1856.  Burials continued in this cemetery sporadically until the 1940’s although the site became less ...

  • Magnetic and ground probing radar measurements for soil pollution mapping in the industrial area of Val Basento (Basilicata Region, Southern Italy): a case study

    Abstract  The joint application of electromagnetic techniques for near-surface exploration is a useful tool for soil pollution monitoring and can also contribute towards describing the spatial distribution of pollutants. The results of a geophysical field survey that was carried out for characterizing the heavy metal and waste disposal soil pollution phenomena in the industrial area of Val ...


  • Estimating soil conductivity for GPR surveys

    The results of a ground penetrating radar survey depends on many factors. In order to get useful data and good penetration, one of the conditions is that the conductivity of the ground is not too high. The conductivity of the material together with the operating frequency and the dielectric constant allow us to calculate the loss factor that is used to roughly estimate the theoretical ...

  • Combined interpretation of radar, hydraulic, and tracer data from a fractured-rock aquifer near Mirror Lake, New Hampshire, USA

    An integrated interpretation of field experimental cross-hole radar, tracer, and hydraulic data demonstrates the value of combining time-lapse geophysical monitoring with conventional hydrologic measurements for improved characterization of a fractured-rock aquifer. Time-lapse difference-attenuation radar tomography was conducted during saline tracer experiments at the US Geological Survey ...

  • Multi-sensor inspection robot shows benefits of pipe penetrating radar - Case Study

    Pipe penetrating radar (PPR), the in-pipe application of ground penetrating radar (GPR) is one of the most promising quantitative pipe condition assessment technologies to emerge in recent years. With most of the underground pipe infrastructure reaching the end of their design life there is a need to provide measurable data in order to establish the extent of rehabilitation required or the timing ...

  • GPR antenna resolution

    How many antennas should I have? We have all heard that question, especially coming from the newcomers to the Ground Penetrating Radar (GPR) technology. The people starting to master this technology are amazed that one has to have so many different antennas for what appears to be the same thing, scrutinizing the earth. What antenna(s) should I choose? ...
