Abstract :
A simple microwave sensor for the detection of the dynamic characteristics of large structure vibration is proposed. It consists of a continuous-wave radar capable of detecting the structure movement by measuring the phase of the back-reflected wave. The system performances have been demonstrated in a case study monitoring a pedestrian bridge.
