Abstract
Structural health monitoring (SHM) using vibrometry is a key technique for the maintenance of bridges and other infrastructure. Conventional methods require in-situ placement of sensors which can be costly and inconvenient. This paper presents a remote monitoring method for extracting vibrational information from very high-resolution SAR data. This was achieved using a combination of a modified back-projection algorithm, spectrogram, and cadence-frequency analysis, which was applied to SAR data of a bridge. The extracted vibrations were validated against synchronous in-situ ground truth measurements.
