    In the last years, the GPS signals have been validated as opportunity signals in a wide range of reflectometry-based remote sensing applications for sea, land or ice scenarios. Recently, the first Galileo satellites have ...
  • Impact of atmospheric anisoplanaticity on earth-to-satellite time transfer over laser communication links 

    Belmonte Molina, Aniceto; Taylor, Michael T.; Hollberg, Leo; Kahn, J. M. (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2017)
    Text en actes de congrés

    The need for an accurate time and position reference on orbiting platforms motivates the study of time transfer over satellite optical communication links. The transfer of precise optical clock signals to space would benefit ...
  • A two-dimensional Doppler-Radiometer for Earth observation 

    Camps Carmona, Adriano José; Swift, C T (IEEE Piscataway, 2000)
    Text en actes de congrés
    Accés obert
    Compared to synthetic aperture radars (SARs), the angular resolution of microwave radiometers is quite poor. Traditionally, it has been limited by the physical size of the antenna. However, the angular resolution can be ...
  • SMOS: a satellite mission to measure ocean surface salinity 

    Font Capafons, Josep; Kerr, Y; Srokosz, M; Etcheto, J; Lagerloef, G S E; Camps Carmona, Adriano José; Waldteufel, P (European Geophysical Society, 2000)

    The ESA's SMOS (Soil Moisture and Ocean Salinity) Earth Explorer Opportunity Mission will be launched by 2005. Its baseline payload is a microwave L-band (21 cm, 1.4 GHz) 2D interferometric radiometer, Y shaped, with three ...
  • Sensitivity equations and calibration requirements on airborne interferometry 

    Mallorquí Franquet, Jordi Joan; Bara, M; Broquetas Ibars, Antoni (IEEE Piscataway, 2000)
    Text en actes de congrés
    Accés obert
    The usage of an airborne interferometric SAR to mass map production is strongly dependent on the capability of performing the data processing in a near automatic mode. One of the main limitations is related to both the ...

    Fabregas Canovas, Francisco Javier; López Martínez, Carlos; Broquetas Ibars, Antoni (2000)
    Text en actes de congrés
    Accés obert
    The activity of the EEF group in the TMR European Project Radar Polarimetry: Theory and Applications will be presented in this paper. We have developed new polarimetric-interferometric retrieval algorithms and enhancement ...
  • Ocean salinity observations with SMOS mission 

    Martín Neira, Manuel; Font Capafons, Josep; Srokerz, M; Corbella Sanahuja, Ignasi; Camps Carmona, Adriano José (IEEE Piscataway, 2000)
    Text en actes de congrés
    Accés obert
    The purpose of this paper is to present the capabilities of SMOS (Soil Moisture and Ocean Salinity mission) for the global mapping of ocean salinity from space. SMOS has been selected by the European Space Agency as the ...
  • Infrared thermograms applied to near-field testing 

    González Arbesú, José María; Aguasca Solé, Alberto; Blanch Boris, Sebastián; Romeu Robert, Jordi (European Space Agency, 2000)
    Text en actes de congrés
    Accés obert
    Electromagnetic fields close to radiant structures can be measured quickly using an infrared camera. Examples of induced fields by wire antennas over a detection screen at distances shorter than one wavelength are presented. ...
  • Microwave imaging techniques for biomedical applications 

    Joisel, A; Mallorquí Franquet, Jordi Joan; Broquetas Ibars, Antoni; Geffrin, J M; Joachimowicz, N; Vall·Llossera, M; Vall-Llossera Ferran, Mercedes Magdalena; Jofre Roca, Lluís; Bolomey, Jean Charles (Vincenzo Piuri and Mario Savino, 1999)
