    • 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 ...

    • Nearly zero inclination geosynchronous SAR mission analysis with long integration time for earth observation 

      Ruiz Rodon, Josep; Broquetas Ibars, Antoni; Makhoul Varona, Eduardo; Monti Guarnieri, Andrea; Rocca, Fabio (Institute of Electrical and Electronics Engineers (IEEE), 2014-10-01)
      Article
      Accés restringit per política de l'editorial
      In this paper, the performance of a nearly zero inclination and low eccentricity geosynchronous synthetic aperture radar (GEOSAR) mission for midlatitude (30 degrees-60 degrees) Earth observation is analyzed. The slow ...

    • Results on spatial-temporal atmospheric phase screen retrieval from long-term GEOSAR acquisition 

      Ruiz Rodon, Josep; Broquetas Ibars, Antoni; Makhoul Varona, Eduardo; Monti Guarnieri, Andrea; Rocca, Fabbio (Institute of Electrical and Electronics Engineers (IEEE), 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper, a high integration gain GEOSAR mission for Earth imaging is presented. The spatial-temporal atmospheric decorrelation issues of a long integration time GEOSAR mission must be carefully studied. The ...

    • Track compensation and calibration of continuous monitoring GEOSAR missions 

      Broquetas Ibars, Antoni; Casado, David; Martín, Roger; Fernández Usón, Marc; Monti Guarnieri, Andrea; Leanza, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      The paper analyzes the problem of achieving a coherent operation in Geostationary SAR (GEOSAR) missions intended for continuous monitoring of land surfaces. In contrast to LEOSAR missions, GEOSAR uses very long SAR integration ...
