This is the 15th European Conference on Synthetic Aperture Radar, which has been held every two years since 1996. Over the years EUSAR, the first dedicated conference on Synthetic Aperture Radar, has become the leading international event gathering world-class scientists and engineers working in the fields of SAR techniques, technology, and applications. EUSAR has accompanied the worldwide developments in high resolution imaging radar and has helped to establish an international community of SAR experts. SAR systems are today an indispensable data source for high-resolution 2D and 3D mapping, environmental and disaster monitoring as well as security related applications. Over the years, the number of SAR missions has increased significantly and there are currently more than 50 operational SAR satellites in orbit. Current SAR missions are operational and, in addition to their scientific exploitation, SAR data and products have gained a considerable share of the commercial EO markets. SAR techniques and information extraction have matured in various domains, enabling operational applications and services, like for example in the European Copernicus programme. Beyond the various sessions on current and future missions, SAR technology as well as imaging and processing techniques, the technical program also includes a number of sessions on data evaluation and applications in various fields.
