SAR antennas on satellites are usually large arrays. Missions like Envisat and TerraSAR-X use active phased arrays with great flexibility and wide swath coverage. Despite the tremendous flexibility involved, such active array systems are however complex, bulky, heavy and hence fairly expensive. At the other end of the scale there is the single beam reflector antenna. The obvious advantages with these systems are the low weight, the potentially large bandwidth and low cost. A SAR system based on a reflector antenna can thus provide high resolution at low cost and - opposed to active systems - at the expense of flexibility and swath coverage. However, this paper describes a feed system for a reflector antenna that will give two sets of multiple dual polarized beams (each set having prescribed beam characteristics), combining some of the flexibility and wide swath coverage of the phased array with the low cost and weight of the reflector system.
