Abstract :
The system that this paper deals about is one stationary bistatic SAR using ultra wide band chirp pulse. Because of the large bandwidth, the echo signal is mixed with the transmitted signal. Then the mixed signal is saved as a raw data. The system has an intrinsic difficulty in processing the raw data due to the long pulse bandwidth. So, it is very complicated to process the data in Doppler domain. This paper proposes an alternative way of processing the data acquired by this kind of SAR system.
