2.2 General description

The IBIS-L system is designed to remotely measure slow displacements with an accuracy

as great as a tenth of a millimetre. The IBIS-L system is particularly suitable for terrain

and structural monitoring applications, with the aim of detecting quasi-static

displacements over long time periods.

The performance of the IBIS-L system depends on the type of configuration used and on

the operative measurement conditions (above all related to the reflectivity of the area

under investigation); however, the best performance characteristics can be defined as

follows:

For Ku band system:

 Maximum operational distance: 4000m;

 Image resolution in distance: 0.75m;

 Angular resolution: 4.3mrad;

 Accuracy in measuring displacements in the viewing direction: 0.1 mm (for

points with a good reflectivity - SNR>50dB – and depending on the impact of

atmospheric variation on the measure).

For X band system:

 Maximum operational distance: 4000m;

 Image resolution in distance: 1.5m;

 Angular resolution: 7.1mrad.

 Accuracy in measuring displacements in the viewing direction: 0.1 mm (for

points with a good reflectivity - SNR>50dB – and depending on the impact of

atmospheric variation on the measure).
