Abstract: The GF-3 satellite, the first C band and multi-polarization Synthetic Aperture Radar (SAR) satellite in China, achieved breakthroughs in a number of key technologies such as multi-polarization and the design of a multiimaging mode, a multi-polarization phased array SAR antenna, and in internal calibration technology. The satellite technology adopted the principle of “Demand Pulls, Technology Pushes”, creating a series of innovation firsts, reaching or surpassing the technical specifications of an international level.
