Get in Touch.Ground-penetrating radar GPR is a geophysical method that uses radar pulses to image the subsurface. GPR can have applications in a variety of media, including rock, soil, ice, fresh water, pavements and structures.

In the right conditions, practitioners can use GPR to detect subsurface objects, changes in material properties, and voids and cracks. A GPR transmitter and antenna emits electromagnetic energy into the ground. When the energy encounters a buried object or a boundary between materials having different permittivitiesit may be reflected or refracted or scattered back to the surface.

A receiving antenna can then record the variations in the return signal. The principles involved are similar to seismologyexcept GPR methods implement electromagnetic energy rather than acoustic energy, and energy may be reflected at boundaries where subsurface electrical properties change rather than subsurface mechanical properties as is the case with seismic energy.

The electrical conductivity of the ground, the transmitted center frequencyand the radiated power all may limit the effective depth range of GPR investigation. Increases in electrical conductivity attenuate the introduced electromagnetic wave, and thus the penetration depth decreases. Because of frequency-dependent attenuation mechanisms, higher frequencies do not penetrate as far as lower frequencies.

However, higher frequencies may provide improved resolution. Thus operating frequency is always a trade-off between resolution and penetration. Optimal depth of subsurface penetration is achieved in ice where the depth of penetration can achieve several thousand metres to bedrock in Greenland at low GPR frequencies. However, in moist or clay-laden soils and materials with high electrical conductivity, penetration may be as little as a few centimetres.

Ground-penetrating radar antennas are generally in contact with the ground for the strongest signal strength; however, GPR air-launched antennas can be used above the ground. Cross borehole GPR has developed within the field of hydrogeophysics to be a valuable means of assessing the presence and amount of soil water.

A patent for a system using radar pulses rather than a continuous wave was filed in by Dr. A glacier's depth was measured using ground penetrating radar in by W. Further developments in the field remained sparse until the s, when military applications began driving research.

GPR-Detector manual.Every GPR system contains one or more antennas that transmit and receive radio frequency waves.

A ball is dropped from a height of 10 feet and returns to a height that is one half

These radio waves penetrate the surface that the antenna is touching or in close proximity to. While much of the signal dissipates, a percentage of the signal comes back to be received by the antenna. This return signal generates visual data that can be recorded, interpreted and manipulated. The data is displayed on a control unit as images that give the operator the ability to see the size of objects and the depths at which they are located. GPR has the same basic principles as a metal detector.

A metal detector sends energy into the earth in up to 17 frequencies. When that energy meets a metallic object, it is translated into a recognizable tone. Similarly, GPR sends out millions of frequencies that return to the antenna and provide visual data of the subsurface and objects buried within.

Radar is sensitive to changes in material composition. Detecting these changes requires movement. In the case of air traffic control radar, the targets are moving, so a stationary transmitter works. GPR systems, however, are designed to locate stationary targets, so one must move the radar to detect them.

They can be used for locating objects with different compositions than their surrounding materials. A PVC pipe, for example, has a different composition than the surrounding soil. Similarly, voids and excavations that have been filled in will also have different compositions than the surrounding soil.

One should note, however, that GPR cannot determine the actual materials that the system is imaging. The MHz antenna is the most widely used for locating rebar and utilities in walls and floors. One should not that, if it is not possible to reach the depth of a buried utility due to soil conditions, it is still often possible to detect the disturbed soil from the original excavation.

A common misconception is that the size of the antenna affects the amount of area covered.

Psychology and learning

The truth is that the size of the antenna relates to the frequency of the antenna and subsequently, the depth that it can penetrate for more information see: How deep does it go? While the signal from a GPR antenna does spread in the direction of travel, the lateral width which it scans per pass is razor thin regardless of the antenna used.

Furthermore, targets are most easily identified with GPR when the survey path is perpendicular to the orientation of the target. For this reason, surveys are usually conducted on a grid in two perpendicular directions:. Grid spacing is determined based on the size of the targets that need to be identified and what sort of results are going to be produced from the survey.

Typical grid spacings can be 1m, 3ft, 5ft, 10ft, 20ft for ground surveys and 1in-1ft. The speed at which data can be collected along a survey line is limited by two factors: 1 time the system requires to process data and 2 surface conditions.JavaScript seems to be disabled in your browser.

MALÅ Ground Penetrating Radar (GPR) Technology Explained

The Gepard ground penetrating radar is using a multiple transmission frequency range starting at 60 MHz up to MHz which is realized by adjustable telescopic antennas.

It furthermore supports many automatic adjustments to optimize your ground surveys on specific soil types, which makes the handling of the Gepard ground radar very easy.

You just set your depth resolution and start surveying. The measured data of the ground penetrating radar is directly transferred to an Android Tablet PC. The Android software receives the data via Bluetooth and displays it immediately on screen.

The software has the capability of integrating a GPS signal, Google Maps, automatic filtering and entering notes for later recollection of specific scan details. Additionally, automatic filtering capabilities are useful to improve the results of your scan and find hidden objects and structures more easily. Due to the integrated GPS all scan positions can be stored along with the scan data.

This optional GPR antenna penetrates much deeper than the MHz antenna and is especially used to detect larger objects which are lying deeper under the ground surface. In contrast to the 60 MHz antenna, the MHz antenna is particularly good for finding small subsurface objects. In that way you can operate your ground radar up to 10 hours continuously without changing the batteries every 3 hours. Log In. My Account My Cart Checkout.
