The space-borne SAR (synthetic aperture radar) payload orbits the earth and can obtain SAR image data without any time and space constraints. Because of these advantages, the development of space-borne SAR has begun in Korea since the 2000s, and the demand for development is increasing further. Until recently, medium and large satellites developed in Korea were active SAR systems operated by electrical beam steering. However, if images should be acquired quickly within a limited time for a region of interest, a passive antenna SAR system is more effective that pointing by platform maneuvering. In this paper, we introduce the development results of a hybrid SAR system mounted on satellites that require high agility and is capable of limited electrical beam steering and its on-ground test and verification results.
