Feasibility of geosynchronous satellites for synthetic aperture radar remote sensing at Ka-BAND
Ruiz, Josep; González, Alba; Broquetas Ibars, Antoni; Monti Guarnieri, Andrea; Carcano, Laura; Fideli, Giorgio; Rocca, Fabbio (European Space Agency (ESA), 2010)
Text en actes de congrés
Accés restringit per decisió de l'autorThis document presents the conceptual design and analysis of a Synthetic Aperture Radar (SAR) system based on geosynchronous satellites (GEOSAR) working at Ka-band. These satellites, apparently orbiting in a fixed position ... -
G-CLASS: geosynchronous radar for water cycle science – orbit selection and system design
Hobbs, Stephen E.; Monti Guarnieri, Andrea; Broquetas Ibars, Antoni; Calvet, Jean-Christophe; Casagli, Nicola; Chini, Marco; Ferretti, Rossella; Nagler, Thomas; Pierdicca, Nazzareno; Prudhomme, Christel; Wadge, Geoff (John Wiley & sons, 2019-11)
Article
Accés obertThe mission geosynchronous – continental land atmosphere sensing system (G-CLASS) is designed to study thediurnal water cycle, using geosynchronous radar. Although the water cycle is vital to human society, processes on ... -
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)
Text en actes de congrés
Accés restringit per política de l'editorialIn 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 ... -
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'editorialWe 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 obertWe 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'editorialIn 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'editorialIn 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'editorialIn 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'editorialThe 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 ...
