Tens of synthetic aperture radar (SAR) satellites are flying over us each day, guaranteeing the health of our planet Earth. Numerous amount of data are being acquired around the world with various modes and configurations, e.g. polarimetric, interferometric, monostatic, bistatic, ScanSAR, etc. Retrieving, processing and operational applications of this data become the bottlenecks. Artificial intelligence and machine vision technology are now revolutionizing the way we tackle this challenge.
