Satellite Monitoring of Railways using Interferometric Synthetic Aperture Radar (InSAR)
There is over 15,600 km of track in the Swedish railroad network. This network is vital for the transportation of people and goods across the country. It is important that this network is monitored and maintained to ensure good function and safety. A tool for monitoring and measuring ground deformat...
