The COSMO-SkyMed payload is constituted of a fixed antenna with electronic scanning capabilities in both the azimuth and the elevation planes. It has been designed to implement three different operation modes in order to acquire the images at the required resolution: Spotlight mode, Stripmap mode and ScanSAR mode. This paper describes the algorithms implemented to focus images acquired in the above three different modes together with the first results obtained using simulated and real data. Telespazio, in cooperation with Consorzio Innova and Digimat, is the prime-contractor of the COSMO-SkyMed CREDO project, in which is foreseen the development of a SAR ground processing chain.ASIAgenzia Spaziale ItalianaAperture antennasAzimuthBandwidthCOSMO-SkyMed SAR sensorCREDO projectChirpConsorzio InnovaConstellation of Small satellites for the MediterrConvolutionData miningDigimatFocusingFrequencyItalian Space AgencyMilitary satellitesSAR ground processing chainScanSAR modeSpotlight modeStripmap modeSynthetic aperture radarTelespazioalgorithmscivil applicationscoastal zone monitoringelectronic scanningfixed antennaimage focussingmilitary applicationsoceanographic equipmentoceanographic regionsprocessing algorithmsradar imagingremote sensing by radarrisk managementsea pollutionspaceborne radarsynthetic aperture radarwater pollution measurementconference paper10.1109/IGARSS.2002.1026770http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=1026770http://ieeexplore.ieee.org/lpdocs/epic03/wrapper.htm?arnumber=102677054dcce088580fe1368eeb038
