    In this paper, the feasibility of a geosynchronous satellite for Synthetic Aperture Radar applications is assessed. The nearly fixed position of geosynchronous satellites offers new features to SAR acquisition such as ...
  • 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
    Open Access
    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)
    Conference report

    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 ...
  • Atmospheric phase screen retrieval from GEOSAR long term acquisition 

    Ruiz Rodon, Josep; Broquetas Ibars, Antoni; Monti Guarnieri, Andrea; Rocca, Fabio (2012)
    Conference report
    Restricted access - publisher's policy
    In this paper, a GEOSAR mission with typical LEOSAR parameters but longer integration time to increase the received power is presented. Such systems can provide images of large areas with continuous monitoring. The revisit ...
  • GEMINI: geosynchronous SAR for Earth monitoring by interferometry and imaging 

    Monti Guarnieri, Andrea; Tebaldini, Stefano; Rocca, Fabio; Broquetas Ibars, Antoni (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    Conference report
    Restricted access - publisher's policy
    In this paper we discuss a preliminary design for a constellation of geosynchronous (GEO) Synthetic Aperture Radars (SAR). The key design concept is to employ one or more pairs of closely-spaced twin receivers flown ...
  • Geosynchronous SAR focusing with atmospheric phase screen retrieval and compensation 

    Ruiz Rodon, Josep; Broquetas Ibars, Antoni; Monti Guerneri, Andrea; Rocca, Fabio (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Article
    Restricted access - publisher's policy
    In this paper, a geosynchronous synthetic aperture radar (SAR) (GEOSAR) mission for atmospheric phase screen (APS) retrieval using a long coherent integration of pulses is analyzed. The nearly fixed position of the ...
  • 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
    Restricted access - publisher's policy
    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 ...
