  • 8. Sentinel-1 has one main operational mode(Interferometric Wide Swath mode) that:• A complete global coverage within 12 days• Preserve Revisit time performance on “high priority” areas (Maritime transportzones and European coast)• Satisfies most currently known service requirements• Avoids conflicts and preserves revisit performance• Provides robustness and reliability of service• Simplifies mission planning & decreases operational costs• Satisfies also tomorrow’s requests by building up a consistent long-termarchiveIn Addition•Mutually exclusive modes are provided for continuity reasons (w.r.t. ERS &Envisat) and for accommodation of emerging user requirements•Two mutually exclusive dual polarisation modes are provided19/06/13Ref.:COPERNICUS Sentinel-1 OperationalConcept

  • 16. 19/06/13Ref.:Spaceborne RADAR’s for Earth observation have shownan increasing and constant growth in the past 5 yearswith the deployment of many important assets (e.g.RADARSAT-2, TerraSAR-X, ALOS-PALSAR, and theconstellation of COSMO-SkyMed).OPENOn this track, new and more challenging programs arereaching, these days, the development phases like theCOSMO-SkyMed second generation.Terrasar-XRadarsatCosmo SkymedIn parallel, research is on-going for the next generations of high performancemulti-mode SAR. The main innovative characteristics are in the fields of:very high resolution;high resolution wideswath multipolarization operation;multi antenna interferometric systems also exploiting higher frequencieslike Ka-band.Innovative concepts are the base to anticipate new market needs and tosupport the development of the new products in the mid/long term periodObjectives & Goals

  • 18. 19/06/13Ref.:High resolution and wide swath coverage are contradicting requirements in SAR system designOn the other hand, many applications may profit of both high resolution and wide swath, e.g.regular land use, vegetation mapping, marine observation, monitoring of Arctic sea ice, as well asdifferential interferometryDigital Beam Forming can be the solution:separate transmit aperture to illuminate a large footprint on the groundreceived signals of each sub-aperture are separately amplified, down-converted and digitizedOPENSAR & Digital Beam Forming
  • 19. 19/06/13Ref.:TAS-I is working at analysing the possibility to develop a Single Satellite Interferometric mission in Ka-band.The use of the Ka-band allows achieving good height information by maintaining a short baselinebetween the two antennas, which can be embarked in a single satellite.The selected configuration is such to provided both measurements in Along-track and Across-trackdirectionMain applications for the Ka-band are:High resolution DEM generationDisaster monitoringUrban areas monitoringOil spillShip detection and identificationOPENMulti-antenna SAR Interferometry in KaBand
