Advanced Space-based InSARR Risk Analysis of Planned and Existing Transportation

The objectives of this project are to: (1) assemble an operational prototype of a powerful space-borne Synthetic Aperture Radar Interferometry (InSAR) displacement monitoring system; and (2) work, with participating state departments of transportation (DOTs), towards integrating this system with current risk assessment practices of existing and planned road and bridge infrastructure. The flexibility and robustness of the advanced InSAR methods contained in this system make it adaptable to specific infrastructure problems and particular environments throughout the United States. The system is thus expected to allow partnering State DOTs to greatly reduce their costs and improve the timeliness for monitoring new and existing transportation infrastructure. Cost benefits above the status-quo of road infrastructure monitoring are achieved through the system’s superior spatial coverage allowing timely reconnaissance monitoring and identification of problem hotspots to efficiently direct on-the-ground monitoring to where it is warranted. Over the last few years Stanford University and MDA, have developed independently a suite of cutting edge algorithms to derive mm-level surface displacement from spaceborne InSAR imagery. We propose to combine our expertise synergistically in a “best of” and complementary way towards prototyping a comprehensive InSAR displacement monitoring system. The proposed research is conducted in close collaboration with State DOTs to guide the evolving prototype to providing efficient and robust unstable ground risk analysis in the planning phase of new transportation infrastructure as well as monitoring the stability and integrity of existing infrastructure.
