Abstract
An interferometric SFCW radar has been recently proposed as an equipment for dynamic testing/monitoring of structures like bridges, towers, buildings and so on. These operations are currently performed by networks of accelerometers. In this paper, the authors report the results of a monitoring on a steel cable-stayed footbridge and a comparison between the two measurement techniques. As the radar measures displacements and the accelerometers measure accelerations, a preliminary discussion about signals and noise is necessary.File | Dimensione | Formato | |
