DI2S Technique for a C-Band SAR System

In this paper the DI2S technique is presented in both Improved Resolution and Multi-Swath implementations. The main advantages of DI2S technique are presented, and a description of the effects on the main SAR image quality parameters is reported as well. The performance of a C-Band SAR System using DI2S Improved Resolution and Multi-Swath are shown with some numerical results. It is described how it is possible to increase the azimuth resolution of long strips or to increase the overall swath acquired by the system.
