The IBIS-FL radar system is an aid 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
