2D monitoring for movements and displacements
The IBIS-FL interferometric radar is a highly innovative technology for 2D monitoring of displacements and movements in slopes and structures. Required to prevent or forecast natural disasters that could affect human lives, monitoring of terrain movements (e.g., unstable slopes, landslides, glaciers) is an increasingly important task for today’s geotechnical experts.
The IBIS-FL, based on Synthetic Aperture Radar (SAR) interferometry, remotely measures the simultaneous displacement of thousands of points over large areas (natural reflections of the slope), without the need for any kind of access to the slope under observation. With an accuracy of up to 0.1mm, IBIS-FL provides a Displacement Time Series for each point. Thanks to the high number and the spatial density of good measurement points, IBIS-FL can also provide Displacement Maps to clearly distinguish stable and moving portions of the area under investigation.
The automatic acquisition and processing of the IBIS-FL data enables the device to provide early warning alerts if movements exceed a selected threshold.
Benefits of the IBIS-FL include:
- Helps identify areas of risk for landslide prevention and landslide mitigation projects by providing a complete and real time stability analysis of a slope
- Provides accurate monitoring of a landslide or a large structure remotely without the need to place valuable equipment in areas of risk
- Reduces the time taken to characterise a landside from the six or 12 months required by traditional instruments to just a few days
The IBIS-FL interferometric radar is supplied along with the Guardian software suite. Specifically designed for critical and background monitoring, Guardian provides automatic real-time processing of radar data, visualisation of displacement maps with multiple analysis options (extraction of time series for displacements, velocity, inverse of velocity), and the possibility to create multiple hazard-maps with user-defined alarm criteria for active monitoring.
IBIS Guardian makes use of state-of the art automatic atmospheric correction algorithms to provide accurate and reliable displacement maps. These maps are fully geo-referenced on a digital terrain model.
The capability to handle long-term projects with large datasets makes Guardian also suitable for the long-term tracking of movements. This proves useful for regulators, the back analysis of slope failure, and more comprehensive geotechnical/geological analysis.
Benefits of Guardian software include:
- User friendly intuitive interface
- Real-time automatic processing
- Automatic advanced atmospheric corrections
- Alarm generation with user-defined levels and multiple alarm criteria
- Long datasets for geotechnical back analysis
- Fully geo-referenced outputs
- 3D interactive data handling
- User defined zones for alarm generation
- Import of multiple digital layers for displaying geological information
- Exportability of outputs to mine planning software
