We are pleased to announce that our associate, Dr Edward Hoppe of the Virginia Transportation Research Council, will be presenting our co-authored paper “Satellite Remote Sensing of Two Post-Tensioned Concrete Bridges in Virginia” between 10:00 am to 11:40 am on August 5th at SHMII-9.

Please join our colleague Cyriac Sebastian and Dr Hoppe for this educational session; learn more about InSAR and how it can be utilized to remotely monitor bridges with millimetric precision. They will be happy to answer all your questions on InSAR and this successful case study.

The study shows how Satellite-based Interferometric Synthetic Aperture Radar (InSAR) technology was applied to monitor bridge displacements over time. The TerraSAR-X radar satellite, orbiting at 515 km above the Earth, acquired data in the Staring Spotlight mode (0.6 m x 0.25 m ground resolution) at 11-day intervals over a period of 16 months. The data were processed with the SqueeSAR® algorithm, resulting in the millimeter range precision of time-displacement series. The results of InSAR analysis indicate that implementing a viable bridge performing monitoring program through the use of satellite radar data is feasible.
