Instantaneous infrastructure monitoring by Earth observation: SAR-based railway obstacle detection

In the framework of the Horizon-Europe project “Instantaneous Infrastructure Monitoring by Earth Observation (IIMEO)” the objective is to design, implement and demonstrate key technological factors of a future satellite-based Earth Observation (EO) system capable of providing functions necessary for instantaneous monitoring of infrastructures in near real time. The system will implement a tiled acquisition of multitemporal SAR images over a railway infrastructure and perform near real-time change-obstacle detection at every new acquisition within one hour after the satellite passes over the area. The tile-based obstacle change-detection multitemporal system is explained in detail.
