Interferometric Processing of Spaceborne SAR Data in Advanced SAR Imaging Modes

Abstract

The paper gives an analysis of ScanSAR and Spotlight data and identifies their common properties and the differences. A generic processing algorithm which consists of the Extended Chirp Scaling algorithm and the Frequency Scaling algorithm is proposed for high precision phase preserving processing of ScanSAR and SpotSAR imaging modes for future spaceborne SAR systems. The ScanSAR processing performance is demonstrated by the inteferometric processing of Radarsat ScanSAR data. The SpotSAR processing is validated using raw data from the airborne experimental SAR-System (E-SAR) of DLR.
