Commercial Synthetic Aperture Radar Satellite（CSAR）is a high resolution compact X-band Synthetic Aperture Radar (SAR) satellite with advanced radar sensors that can operate under any weather or visibility conditions and in multiple operation modes. Features of agile, rapid response, and low cost, CSAR is developed through flight proven technologies and equipped with off-the-shelf instruments. CSAR is conceived as the best candidate to meet civil (environment, civil protection, Oil&Gas) and specific targets identification (Airplanes, Ships, vehicle, bridges, pipelines).    

CSAR builder, SAST (Shanghai Academy of Spaceflight Technology) has teamed with professional SAR engineers to provide a turn-key space-borne system which aims at satisfying the specific requirement of customers through every step of satellite manufacturing, launching, and applications.
