Abstract :
In this paper, a SAR system with a method of Digital Beamforming(DBF) was offered, which can realize both wide swath and high resolution at the same time. This research is based on the Displaced Phase Centers Multiple system, which adopt the DBF method at the receive, and is combined with the properties and demands of near space., and through the optimization of the design and overall consideration of the antenna size,pulse repetition frequency(PRF) and the ambiguities etc, the analyzed results demonstrate that it is possible to get wide swath and high resolution, what´more, such a system combined with the advantage of the near space will create a great superiority, and is of great reference value of the near space development and applications.
