Remote static and dynamic monitoring with accelerometer to mitigate large external vibrations.


An advanced microwave interferometry based system for remote static and dynamic monitoring, IBIS-FS Plus inferometric radar is used on bridges and other structures including buildings, historical monuments and towers. An accelerometer version of IBIS-FS, this radar mitigates the effect of large external vibration sources on results.

In static, the IBIS-FS Plus is ideal for:

  • Structure load testing;
  • Structure displacement and collapse hazards;
  • Cultural heritage preservation.

In dynamic, the IBIS-FS Plus is best used for:

  • Structure resonance frequency measurements;
  • Structural modal shape analysis.

In either state, the IBIS-FS Plus features:

  • Remote sensing: Real-time remote sensing at up to 1 km with no need for equipment to be installed on the monitored structure.
  • Accurate measurements: Measures displacements of as little as 0.01mm @ 0.5km range. No standard instrument can achieve such accuracy.
  • Ground vibration removal: Built-in accelerometer to cancel the self-induced vibrations transmitted to the radar from the ground.
  • Sampling: Structural vibration sampling up to 200 Hz.
  • Always operational: Operates day and night and in all weather conditions.

Benefits of the IBIS-FS Plus include:

  • Accurate measurements even when the system is installed in places with large ground vibrations;
  • Increase structural health monitoring efficiency through the use of a non-invasive vibration monitoring technique;
  • Accurate and remote real-time monitoring of structural vibration and natural frequencies;
  • Reduces the time required for static or dynamic bridge structural testing to just a few minutes
