Abstract :
This paper presents a new system implementation of an active antenna for a forward looking airborne SAR with digital beamforming on-receive-only. 56 receiving antennas are used together with one transmit antenna where each antenna illuminates the whole covered swath. A simplified hardware configuration is achieved by switching through the receiving array, thus sequentially recording return signals from each receiving antenna. The system was built under contract from the DLR, Oberpfaffenhofen, Germany.
