发明名称 SYNTHETIC APERTURE RADAR (SAR) SYSTEM
摘要 In a multi-channel Synthetic Aperture Radar (SAR), a SAR group antenna with several receivers is reproduced by means of time-multiplexing a receiver, wherein each receive channel is assigned an antenna segment and, parallel to multiplexing a receiver, a different amplitude allocation is given to the antenna. More "virtual" channels than are physically present are provided, which is achieved by an increased pulse repetition frequency (PRF). The amplitude allocation of the antenna can be assigned during transmission, during receiving and during transmission and receiving. Multiplexing can be advantageously expanded by operating receivers in parallel mode and modifying the so-called "burst-mode technique", which is otherwise used in Scan-SAR systems. Used in multi-channel SAR and SAR interferometry, especially satellite applications.
