IBIS-FM Interferometric Mine Slope Radar

• Highest spatial resolution: 0.5m x 4.4m resolution cell @1 km, resulting in the detection of smaller failure areas.


• Longest operating range: From 10 m up to 4000 m.


• Extremely broad coverage of pit walls: Can cover an area of around 5 km2 @ 2 km.


• Low acquisition time: Just a few minutes for a full resolution scan at long range (2.5 minutes @2 km).


• Long term monitoring: Through either permanent installations away from blasting restricted areas or by precise re-positioning of the system.


• Fully self-powered operation: Using a combination of solar panels and batteries, only switching to a diesel generator as a back-up.


• High in-service availability: A limited number of moving parts and low maintenance requirements help to keep down-time to a minimum.


• Fully remote operation: Provided by a wire-less radio link.


• Advanced atmospheric estimation.


• Fully tested in harsh mining environments.

Guardian Software










IBIS-FM is supplied along with the Guardian software suite which is specifically designed for critical and background monitoring. Guardian provides automatic real-time processing of radar data, visualization 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 which 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 which is potentially useful for regulators, the back analysis of slope failure and more comprehensive geotechnical / geological analysis.
