Abstract
In this lecture, the principle of Synthetic Aperture Radar (SAR) is presented and explained, with a discussion of instrument aspects, data flow, and potential capabilities to “see at microwave frequency”. Information about past and operational microwave SAR instruments of the European Space Agency is used as illustration material with data examples. Interesting interferometric observations permit to Today such space-based instruments take part in the important European program “Copernicus”. Interferometry plays an important role, based on various scenarios. One can use the same instrument time sequential to distinguish between the two observation moments, of interest to analyze sudden changes in between, be it due to Earthquake or flooding or other impacting event and analyze with precision the differences.
