Interpreting Satellite Radar for Bridges: Integrating MT-InSAR with Physics-Based and Data-Driven Models for Scalable Structural Health Monitoring
Abstract Multi-Temporal Interferometric Synthetic Aperture Radar (MT-InSAR) has matured into a credible, non-contact technique for monitoring bridge deformation from individual structures to regional portfolios. The main challenge for routine engineering use is no longer measuring millimetre-scale line-of-sight (LOS) displacement, but interpreting those measurements into defensible statements about structural condition. This review addresses that interpretation problem by synthesising the physical and algorithmic f …
