Abstract
In Alenia Aerospazio has been developed a demonstrator for SAR data analysis and automatic target recognition (ATR). The new version we present in this paper introduces some new characteristics. A better sidelobes suppression via the locally variant apodization and a new CFAR processor using a cell-average or an ordered-statistics detector are integrated to the pervious structure to improve the preliminary target detection i.e. the candidate ship detection. After this step and in parallel with the ship wake detection we implement a new and independent way to recognize moving objects with a following improvement in detection performances: the estimation of residual coherent phase error locally present on the focused image, due to the target motion. The test images are referred to the SIR-C/X-SAR mission.
