Requirements for an L-band SAR-mission for global monitoring of tectonic activities

SAR interferometry is a well established technology for mapping tectonic activities from space. In this study a mission concept is investigated that provides a global monitoring capability of geo-tectonic threads. Due to the requirement of long-time interferometric coherence of the mapped surfaces an L-band system is proposed. Four scenarios are defined and the respective product requirements are given for each of them: tectonics/earthquakes, tectonics/volcanoes, landslides, and urban subsidence.
