FAQ
What does GPR stand for?
GPR is the acronym for Ground Penetrating Radar, also known as Georadar, Ground Penetration Radar, or Ground Probing Radar.
What is GPR?
GPR is a compact device that scans the subsurface in a non-destructive way. It can penetrate the surface from a few cm down to tens or hundreds of meters, based on soil conditions and antenna characteristics.
How does GPR work?
GPR emits electromagnetic (EM) waves to the subsurface and calculates the time these waves need to travel through the various subsurface material and get back to the GPR receiver. This two-way travel-time, along with a few other parameters such as the dielectric, provide the user an estimate of the target depth.
What applications does GPR cover?
GPR is a very useful tool in a variety of applications. Most popular uses of GPR are the non-destructive testing and mapping of objects inside the concrete, such as rebars, pipes, ducts, and cables. Other applications are infrastructure assessment (bridge decks, roads), utility location, archaeology, forensics, environmental studies (mapping contaminants), shallow geology and geophysics, mine exploration and safety, transportation (pavement thickness and density, ballast fouling), agriculture, military (UXO), sedimentology, glaciology, quarrying, space exploration.
Will my GPR work as standalone unit or can it also complement other methods?
Both. GPR can be used as a standalone unit if you work on specific applications and you are happy with a limited set of feedback and information. However, it is not a tool for every job you may have onsite. In concrete applications, GPR can be used in combination with Ultrasound Tomography (Pundit Array: https://bit.ly/3cBBeTE) and Eddy Current Rebar locators (Profometer: https://bit.ly/39B0QhJ) to get a comprehensive approach.
What is dielectric value?
Dielectric, also known as relative permittivity, is a unitless value that determines how fast EM waves travel in a specific medium. Its values range from 1 to 81, with lower values being better for GPR. Air, which is the best medium for radar waves has a value of 1 and seawater has a value of 81. Metal objects have infinite dielectric.
Can GPR find all targets?
GPR can detect metallic and non-metallic targets below the surface. However, certain limitations exist, like the depth to target limitation. The rule of thumb is that GPR can detect almost any target if it is at least one inch (2.54cm) in diameter and is buried at one foot (0.30m) or shallower. For example, it may be impossible for GPR to locate a 3-inches (7.6cm) plastic pipe down to 6 (1.82m) feet depth. Metallic targets are doing better with this rule.
Can GPR penetrate metal?
No. Metal is a perfect reflector of GPR with an infinite dielectric, thus all EM energy is being reflected to the radar. Differently to GPR, Ultrasonic tomography can penetrate metal with only a partial reflection allowing to ā€œseeā€ behind metal objects.
What affects my data quality?
Anything that emits at the same frequency range as GPR, from around 10MHz up to 6GHz, can be a potential source of noise for your data. Cell phone towers are a main source of interference. Collecting data close to cell phone towers will introduce significant noise levels into your data. Two-way radios, walkie-talkies and similar devices are also a source of interference. Also, the way an antenna is built and/or the method it uses to collect data can introduce noise into your data.
What does not affect my data quality?
Bluetooth, GPS, Wi-Fi are not a source of interference and therefore you can use them with no problems when collecting GPR data.
How deep can GPR penetrate the subsurface?
This depends on the soil conditions, and most importantly on the dielectric and the electrical conductivity. The higher the water and salt content in a material, the shallower a radar penetrates the ground. Pulsed systems face the frequency dilemma on top of the soil dielectric/conductivity. Users must select a specific frequency, and this adds an extra limitation to the max depth penetration. The higher the frequency&nbsp;the shallower you penetrate, but the better the resolution you get. On the other hand, the lower the frequency the deeper you penetrate, but the resolution gets worse. Stepped Frequency Continuous Wave (SFCW) systems do not face this frequency dilemma.
Will my GS8000 GPR collect any data if I do not move?
No. Data collection on GS8000 is triggered by wheel movement. If you do not move the radar, then no data collection is happening. The wheel is acting also as an odometer, giving local coordinates on the x-axis direction.
Do I need to calibrate my GS8000?
No. GPR self-calibrates each time you turn it on. There is no need to send your unit back to a repair/calibration center.
Does GS8000 work on all surfaces?
GS8000 comes with a rugged cart and can work on most surfaces without a problem. If the wheels can move, then your antenna can collect subsurface data. However, you must keep in mind that very uneven surfaces can create some pseudo-targets that can be corrected with a GPS. You must also be aware that moving over conductive materials, e.g., aluminum, copper etc. can limit or even zero the penetration depth of your radar antenna.
What is the difference between 2D and 3D data?
2D Data are collected over single lines and give you a B-scan or radargram of the specific profile the radar has covered. The B-scan is a graphical representation of radar data (sequence of A-scans or traces) on an x-axis which represents the distance and a z-axis which represents depth (or time). 3D data are collected over an area (e.g., using a grid of specific dimensions) and result in a data cube with two directional axis (x and y) and one depth axis (z). Such data cube is often sliced on different planes (C-scans) during data visualization. The most intuitive of those are horizontal cuts (top-down view) called time or depth-slices which are often used for interpreting subsurface targets.
I have an EM locator, why should I buy a GPR?
Because GPR can detect all targets, metallic and non-metallic and features like layers, rebars, and voids in the subsurface. EM locators will detect targets made from conductive materials and will need to energize other targets in order to trace them, which is not easy, nor flexible. Typically, GPR gives a deeper penetration, can provide B-Scans and A+B-scans of the subsurface and export this info into maps. If you have already an EM locator, adding a GPR will make your work easier, faster, and more accurate on site.
Can I connect GPS with my GS8000?
Yes. GS8000 comes with standard GNSS receiver that syncs with GPR data automatically. You donā€™t have to connect external data loggers or buy third party location systems.
Is GPR safe for operators?
Yes. GPR, unlike other testing methods such as radiography, is totally safe for the operator. Our antennas are shielded and emit most of the EM energy down to the subsurface. Total emissions from GPR are a tiny fragment of what a modern cellphone emits. You can get more information here https://www.osha.gov/radiofrequency-and-microwave-radiation and here https://bit.ly/2YoHkP7
Is GPR environmental-friendly?
Yes. As a non-intrusive technique, GPR does not alter or burden the environment and can be used in sensitive areas or environmental fragile areas without a problem.
Do I need a license to carry a survey?
That depends on the area you want to work and the local regulations. However, GPR surveys do not typically require a safety clearance because the method itself is not dangerous. If however, you work at a dangerous or sensitive area, e.g., refinery, mine, military or archaeological site you will need a license anyway. In order to comply with local rules please consult a local agency who can guide you accordingly.
Do standards exist for GPR surveys?
Yes. ASTM has published the standard ASTMD6432ā€“19, as a guide for using GPR for subsurface investigation. You can get more info here https://www.astm.org/Standards/D6432.htm There are several other standards related to specific applications of GPR.
Is Screening Eagle GPR certified?
Yes. Our equipment meets CE, IC, FCC, ETSI-EN RSS-220 and RoHS regulations.
Can I transport or ship my equipment with safety?
Yes, unlike the competitors who use batteries characterized as dangerous goods for aviation, Screening Eagleā€™s GPR use standard rechargeable NiMH C-batteries which can fly with you, ship with no restrictions, and most importantly can be bought locally if needed.
What is the most used data format for GPR?
Typically, GPR exports data in the SEG-Y format. This can be easily converted to other formats like .xls, .dxf or .kml if needed for further visualization of data.
What is GNSS positioning and how accurate can it get?
GNSS stands for Global Navigation Satellite Systems. The most famous constellation is GPS, but nowadays it is possible to receive simultaneously the signal from multiple constellations, such as Glonass, Galileo, and BeiDou. This brings the numbers of satellites visible in the sky close to 100, which results in higher chances of getting a 3D position even in non-open sky conditions. A professional-grade GNSS system is also able to process differential corrections, which are normally broadcasted from a server. This is a real-time computation that results in a corrected position as accurate as a few centimeters.
What is Stepped Frequency Continuous Wave?
Unlike Pulsed-GPR broadcasting a signal centered around one frequency, resulting in a trade-off of resolution and depth for inspecting, stepped frequency continuous wave (SFCW) has the advantage to broadcast an ultra wide-band range of modulated frequencies. The combination of all frequency response enables detection of objects from shallow to deep depth in one scan.
What is SEGY format?
The SEGY (sometimes SEG Y) file format is a commonly used data standard for the exchange of geophysical data. It is mainly used for Seismic data, but also for saving GPR raw data. Our GPR SEGY files can also be used for post-processing data.
