This is the latest high speed flexible Groundvue multi-channel. It can be used in any configuration, from a trolley, from a vehicle, hand towed. Antennas can be attached, detached for another application, changed around at will. And the viewing parameters can be changed during operation. This is the radar used to detect fibre optic cables (video coming soon) and also to accurately track the direction of utilities at one sweep.
High Speed Multi-Channel
Up to 1,600 scans per second
Data collection speed consistent with traffic speeds
Simultaneous triggering without cross channel interference
Up to 8 channels: select any number from 1 to 8
Independent time sweep (probing depth in nanoseconds) on every channel
Independent antenna frequency on every channel
Integrated GPS input (independent of laptop)
Wi-Fi
Wi-Fi operation
Ethernet cable for frequencies >1GHz where Wi-Fi cannot be used
Flexibility
This is a multi-channel GPR which can be used in single or multifrequency modes
It can also serve as a high density array in either single or multifrequency.
The antennas can be positioned in any configuration that the user requires.
Up to 8 channels: select any number from 1 to 8
View any number of channels on screen simultaneously – from 1 to 8. Change the view during survey without affecting the data recording.
Selectable wiggle trace on any channel to monitor the data quality.
Gain settings can be altered during the survey. The operator can change the gain settings whenever this is useful during the survey. This does not affect the recorded data in anyway
Up to 4 receivers can be used with 1 single transmitter.
Since the antennas are simultaneously triggered, transmission velocity can be calculated automatically from the multiple receiver data.
This multi-channel can be used for 3-dimensional SAR processing
Efficient Economic Hardware Design
Clear Data – Internal stacking in the receivers with jittered PRF reduces external interference, resulting in clearer data and less requirement for processing
Modular – This multi-channel can be used for multiple applications. Why buy two systems if one will do?
Multi-functional – The same system can be used from a trolley or from a vehicle or even hand pulled antennas from the same system
Low Power Consumption – Only 1A at 12V (12 watts)
Fully Screened – To prevent stray emissions and protect from external transmission
Efficient Economic Software Design
Windows based software
Raw data recorded – No pre-filtering required
Utility mark up function – For locating utilities on-site
On-screen Tzero correction – The correction is automatically stored in the header file for automatic import into processing package (reduction in processing steps)
On-screen Background Removal
Added Value Tools
Crack Depth Measurement – Any GPR can detect areas of generalised cracking. The adapted crack detection head is used for:
Accurate detection of joints in concrete
Depth measurement of surface (top down) cracking
Detection of subsurface (bottom up) cracking on roads, airports and in structures such as concrete loading bays and flat roofs
Automatic Velocity Calibration – Groundvue antennas are simultaneously triggered, not sequentially, and without cross channel interference. Using multiple receivers connected to a single transmitter, continuous comparative data is created. Layer tracing generates the information needed to calculate transmission velocity for the full length of the data collected. In the process, any anomalous areas show clearly.
Antenna Frequencies
6GHz, 4GHz, 1.5GHz, 1GHz, 400MHz and 250MHz. 100MHz currently under development.
Regulation Compliance
ETSI compliant (CE marked)
FCC compliance available on request
Ancillaries
A laptop or tablet (Windows 8, 7 or XP) is required for radar operation and data storage.
A long term data storage system is essential
A basic 12V battery charger is needed to charge the radar batteries.
Optional Extras
Analytical software – the ReflexW package – is also available.
Details on request
Groundvue data is also compatible with Roadscanners, GPR-Slice and Geoscanners software.
Data formats can be supplied to other software suppliers on request.
