Accurate Monitoring of Pipe and Structural Vibrations by Remote RADAR Observations

The paper describes an innovative RADAR-based methodology to monitor vibrations in pipes and structures. RADARs sense vibrations from zero to thousands of kHz with a spatial sensitivity that goes down to a few micrometers in the best cases and they never saturates even for very large motions. Furthermore, they do it remotely, say tens of meters. The paper provides a critical analysis of performance of such technique and a cross-validation with both controlled vibration in laboratories and measures from accelerometers in campaigns in compression gas stations.
