Design of Resolution for InSAR System Based on Formation-Flying Satellites
摘要
Abstract
According to the pulse compaction technology and the SAR imaging principles, and on the basis of the introduction of the SAR resolution definition, the reasons affecting the resolution of the InSAR system based on formation-flying satellites has been ananylsed, and it' s because of the existing of the across-track and alongtrack baselines. In the imaging disposing process, in order to insure the precision of the interferometric phase,the decorrelation pre-filtering process must to be done, but it will cause the system imaging bandwidth narrow and the resolution low. A resolution designing method for the InSAR system based on formation-flying satellites was proposed firstly, and then the influence on the resolution was ananylsed by the method.关键词
