HIGH RESOLUTION, LONG-RANGE SOLUTION
Designed to identify long-range risks and hazards, the SSR-SARx is a long-range and high-resolution system for the monitoring of tailings dams. The SSR-SARx is a 2D Synthetic Aperture Radar (SAR) designed to detect even the smallest of movements over long periods of time.
The SSR-SARx boasts stunning aperture resolution with pixels of 0.083 degrees by 75 centimetres; able to detect fast and slow moving failures with 50 per cent more resolution than any other SAR system on the market.
The SSR-SARx glides on a 3 metre rail without starting and stopping in an ‘on-the-fly’ acquisition method, allowing an end-to-end SAR scan speed of just two minutes.
Taking only 40 seconds to acquire the data, coupled with in-built processing at the radar, ensures no latencies or delays in the transfer of data to the Primary Monitoring Point. The fully-processed data is immediately available for viewing and alarming at the end of every two minute scan; a feature specifically unique to GroundProbe.
GroundProbe’s renowned, intelligent processing algorithms reduce the size of raw SAR data by 96.5 per cent, to maintain the smallest possible file size, allowing users to critically monitor even over a slow WiFi link.
Its in-built processing and lightweight transfer means there is no need for unreliable laptops to be left in the pit, nor super computers in the office.
With GroundProbe’s propriety radar processing technique, the SSR-SARx can monitor very slow movement, whereby gradual deformation is monitored over long periods of time, which may not otherwise be detected by short-term monitoring campaigns.
By automatically creating three wall folders – scan by scan, 8 hours or 24 hours – long-term or campaign monitoring capabilities are provided.
The SSR-SARx facilitates permanent, continuous 24/7 monitoring over many years through its small and light system with low power consumption.
The SSR-SARx includes a high resolution, integrated imaging system for real-time photographs that are co-registered with the radar data; a technique unique to and patented by GroundProbe.
When the data is visualised, the deformation heatmap is draped over the high resolution image. By clicking on any part of the image, movement can be reviewed and assessed live, with confidence.
Without the need for georeferencing, or importing a DTM into the radar, the SSR-SARx can commence monitoring straight away.
A key benefit of interferometric-based radar technology, the SSR-SARx doesn’t lose measurement accuracy as range increases. Deploy the radar 10m or 4,500m from the area of interest, and its sub-millimetre deformation measurement accuracy remains.
GroundProbe has a world-class support network, Geotechnical Support Services (GSS) that actively assist our customers in getting the most out of their asset.
On request, and customised to suit specific site needs, GSS can:
- Conduct advanced training and on-going development for on-site staff
- Deliver regular, detailed reports containing comprehensive analysis and interpretation of radar data
- Provide a complete remote monitoring solution – real-time, 24/7 support from a central, remotely-located office
- Provide a complete local monitoring solution – in-person, on-the-ground monitoring, flying in and out as needed
- Offer competency-based training into the application of alarms and the integration of alarm thresholds
The antennas are more robust and reliable, being unable to bend and protruding less, and are operable in rain without fear of water pooling and disturbing the radar image.
An upgrade from standard horn antennas, the solution has been specifically designed for the Ground-Based Interferometry band 17.2Ghz and can be used worldwide, meeting global GBInSAR ETSI specifications.
