  • 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 ...

  • Forensic applications including mapping and classification of tsunami sand deposits and sand dunes with ground penetrating radar

    The coastal region experiences erosional, transportational and depositional events during mega events such as tsunami. The onshore deposits are significant in determining the past events of high–energy events in the coastal region. The Optically Simulated Luminescence (OSL) dating of the sediments by combining Ground Penetrating Radar (GPR) records will reveal the past tsunami events. OSL dates ...

  • Adaptive Kinetic Antenna

    Abstract - The paper describes a method of kinetic antenna development that can be adapted to environmental conditions. The kinetic antenna is a variety of integrated into impulse generator active antenna that is used for kinetic energy accumulation. Such antennas are attractive for ground penetrating radars owing to its possibility to change radiation spectrum in according with ground ...

  • Topographic Correction of GPR Profile Based on Odometer and Inclinometer Data

    Abstract— Usually, data obtained by ground penetrating radar (GPR) are displayed as a rectangular 2D picture (profile), vertical and horizontal axes of which are proportional to depth and traveled distance, respectively. Surface, generally, is not horizontal, that leads to distorted view of irregularities in the GPR profile. To eliminate these distortions a topographic correction is used. ...

  • 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? ...

  • 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 ...

  • Locate buried monitoring wells case study

    A Phase II Environmental Site Investigation was being conducted at a gasoline station in Fort Myers, Florida. In order to minimize costs, our client intended to use several existing on-site monitoring wells rather than installing new wells. However, five of the existing wells had been covered with asphalt and were no longer visible. GeoView was tasked with performing a shallow geophysical study ...

  • Optimal GPR antenna selection

    It is common knowledge to anyone practicing Ground Penetrating Radar (GPR) technology that lower center frequency antennas mean higher penetration and lower resolution. In the same way it is correct to say that higher center frequency antennas mean lower penetration and higher resolution. This is without any doubt an axiom that provides us with a rule of thumb on what to use and what not to use ...

  • 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 ...
