  • Mining Emissions Effectively Monitored with Micro Pulse LiDAR Technology

    Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining should be monitored and kept to a minimum; however, it is very challenging to measure the levels of contaminants in the ...

  • Micro Pulse Lidar: Perfect Tool for Atmospheric Research

    Micro pulse style lidars are active remote sensing tools proven to be highly useful in atmospheric research. This style of backscatter lidar has been around for decades; however, incremental improvements in photon counting, sensitivity, polarization, optical filters, coatings, and precision machining of each element support increasingly accurate analysis. Each iteration of the ...

  • Top 5 Differences between Micro Pulse LiDAR and Ceilometer Technology

    If you are evaluating backscatter LiDAR sensors for measuring aerosols, cloud vertical structure, and planetary boundary layer (PBL) heights, what factors should you consider in your comparison? It really comes down to a choice between the traditional analog technology used in ceilometers and the more recent advanced technology found in Micro Pulse LiDAR (MPL) sensors. ...

  • 3D model evolution of a leak based on GPR image interpretation

    This paper presents some aspects of the time propagation of underground water leakage in controlled laboratory conditions using a drilled polyvinyl chloride (PVC) pipe and interpreting ground penetrating radar (GPR) images. GPR pre-processed images are interpreted for easy identification and extraction of surfaces and volumes of water leakage. Finally, the temporal evolution of a water leak is ...

  • Topography correction and the importance of applying it to the GPR records

    Introduction The subject of this article is to introduce you to the importance of applying topography correction to GPR (ground penetrating radar) records and to inform you about the possible ways of doing it. Although the basis is taken from the geography terminology, I would like to emphasize that the usage of terms ”topography correction” and ”topographic ...

  • Pulse Shapes from Ground Penetrating Radar

    A number of technical reports have discussed the use of ground penetrating radar equipment in examining highway structures for deterioration. Several of these reports provide expressions or calculational techniques that purport to describe the shape of the radar pulse returning from voids within the structure, such as the thin air gap at a delamination within a concrete bridge deck or the larger ...

  • Utility locating at a Gasoline station case study

    As part of an Phase II Environmental Site Assessment at a gasoline station, GeoView was tasked with locating and mapping the  utilities within the boundaries of the property. The utilities included electrical lines, communication lines, PVC and metal water lines, sewer lines and fiberglass fuel lines. The property did not have any as-builts to reference. As standard procedure, GeoView ...

  • 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 ...

  • The VIY-2 Ground Penetrating Radar

    Abstract The VIY-2 ground penetrating radar (GPR) with unique sounding possibilities and use simplicity is presented at this paper. The VIY-2 GPR combines all units (synchronizer, transmitting and receiving modules, power supply and antenna system) into single case. The VIY-2 GPR communicates with computer via standard interface RS232 or USB 1.0. Utilized by the VIY-2 GPR technical solutions ...

  • Meltwater flow through a rapidly deglaciating glacier and foreland catchment system: Virkisjökull, SE Iceland

    Virkisjökull is a rapidly retreating glacier in south-east Iceland. A proglacial lake has formed in the last ten years underlain by buried ice. In this study we estimate water velocities through the glacier, proglacial foreland and proglacial river using tracer tests and continuous meltwater flow measurements. Tracer testing from a glacial moulin to the glacier outlet in September 2013 ...

  • 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? ...
