Health status of ancient buildings:interferometric radar NDT inspection

摘要

In this paper an innovative NDT methodology for the monitoring of the health condition of ancient building is presented. The methodology is based on the reconstruction of the dynamic behaviour of the structure using an interferometric radar, that is a non-contact sensor able to monitor in real time the displacement of several points belonging to the building. The monitoring of any modal parameters change into the years is of use for the structural integrity assessment.
