Perspectives and visions for future SAR systems

It is shown how far new SAR techniques, technologies and system principles, which at present are under consideration or under development, respectively, will fulfil future user requirements. Starting from the status quo, the expected development of future SAR techniques and technology is presented, leading to the vision of an autonomous, global reconnaissance and remote sensing system with integrated communication and positioning capability. This system will have central illuminators together with a synchronised fleet of both airborne and spaceborne receivers, which enable continuous availability with a nearly global coverage, and dedicated information transfer to specific users in real time.
