    • Advanced radar geosynchronous observation system: ARGOS 

      Monti Guarnieri, Andrea; Broquetas Ibars, Antoni; Recchia, Andrea; Rocca, Fabio; Ruiz Rodon, Josep (Institute of Electrical and Electronics Engineers (IEEE), 2015-07-01)
      Article
      Accés obert
      The Advanced Radar Geosynchronous Observation System is proposed to be a multiple-input–multiple-output synthetic aperture radar (SAR) system hosted on a swarm of minisatellites in quasi-geostationary orbits. The system ...

    • An efficient method for the azimuth compression of geosynchronous SAR data through sub-apertures processing 

      Belotti, Michele; Broquetas Ibars, Antoni; Leanza, Antonio; Monti Guarnieri, Andrea; Recchia, Andrea; Rocca, Fabio; Ruiz Rodon, Josep; Tebaldini, Stefano (Institute of Electrical and Electronics Engineers (IEEE), 2013)

      We propose an efficient method for the azimuth compression and Atmospheric Phase Screen estimation of Geosynchronous SAR data. The method is based on the iterative processing of sub-apertures of increasing size, allowing ...

    • Assesment of atmospheric phase screen impact on Geosynchronous SAR 

      Recchia, Andrea; Monti Guarnieri, Andrea; Broquetas Ibars, Antoni; Ruiz Rodon, Josep (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The paper evaluates the effects of Atmospheric Phase Screen on focused Geosynchronous SAR data. We derive theoretical models for the resolution, the interferometric de-correlation and the induced clutter in presence of an ...

    • Bistatic geosynchronous SAR for land and atmosphere continuous observation 

      Ruiz Rodon, Josep; Broquetas Ibars, Antoni; Monti Guarnieri, Andrea; Recchia, Andrea (VDE Conference Publications, 2014)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      In this paper the bistatic SAR observation from low-eccentric nearly zero inclined geosynchronous orbits (GEOSAR) is studied. Two operation frequencies have been analysed with different compromises between spatial resolution ...

    • Impact of clutter decorrelation on Geosynchronous SAR 

      Recchia, Andrea; Monti Guarnieri, Andrea; Broquetas Ibars, Antoni; Ruiz Rodon, Josep (VDE Conference Publications, 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      We discuss the effects of the clutter on a Geosynchronous SAR system exploiting long integration times (from minutes to hours) to counteract for spread losses and increase azimuth resolution. Only stable targets will be ...

    • Impact of scene decorrelation on geosynchronous SAR data focusing 

      Recchia, Andrea; Monti Guarnieri, Andrea; Broquetas Ibars, Antoni; Leanza, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2016-03-01)
      Article
      Accés obert
      We discuss the effects of the clutter on geosynchronous SAR systems exploiting long integration times (from minutes to hours) to counteract for two-way propagation losses and increase azimuth resolution. Only stable targets ...

    • Internal clutter motion impact on the long integration GEOSAR acquisition 

      Ruiz Rodon, Josep; Broquetas Ibars, Antoni; Makul, Eduardo; Monti Guarnieri, Andrea; Recchia, Andrea (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper, the impact of the internal clutter motion in GEOSAR acquisitions is analyzed. A nearly zero inclination with low eccentricity geosynchronous orbit is considered and, therefore, long integration, in order of ...
