A STUDY FOR COSMO-SKYMED SAR MULTI-BEAM OF SECOND GENERATION(MSAR-2G)

摘要

This paper discusses the potentialities obtained by splitting the antenna of the COSMO-SkyMed SAR - developed byrnAlenia Spazio under contract of Italian Space Agency and Italian Ministry of Defence - into multiple sub-apertures. Thernmodified sensor is shown to allow: (a) clutter cancellation and detection of slowly moving ground targets forrnsurveillance purpose, (b) sea current/wave monitoring by along-track SAR interferometry, ( c ) relocation of movingrntargets in high resolution SAR images, and ( c ) fully polarimetric imaging. The practical implementation of the possiblernmodification is also discussed together with the new operational modes design.
