Descalloping of ScanSAR Image using Kalman Filter based Technique

The Scan mode Synthetic Aperture Radar (ScanSAR) is a powerful and widely used acquisition mode for Earth observation due to its large imaging swath and short revisit time. These characteristics make ScanSAR mode more advantageous over strip and spotlight SAR aquisition modes. The particular ScanSAR operating mode can cause two major artifacts in processed imges known as scalloping and inter-scan banding (ISB). In this paper a novel technique proposed by mahboob and jie chan to remove scalloping using kalman filter is applied to RISAT-1 medium resolution (MRS) ScanSAR image. The obtained results show the effectiveness of proposed technique.
