    ESA's Soil Moisture and Ocean Salinity (SMOS) mission, launched 2-Nov-2009, has been in orbit for over 6 years, and its Microwave Imaging Radiometer with Aperture Synthesis (MIRAS) in two dimensions keeps working well. The ...
  • Nodal sampling: a new image reconstruction algorithm for SMOS 

    Gonzalez Gambau, Verónica; Turiel, Antonio; Olmedo Casal, Estrella; Martinez, Justino; Corbella Sanahuja, Ignasi; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2016-04-01)
    Article
    Accés obert
    Soil moisture and ocean salinity (SMOS) brightness temperature (TB) images and calibrated visibilities are related by the so-called G -matrix. Due to the incomplete sampling at some spatial frequencies, sharp transitions ...
  • Scattering and emissivity of rain events using boundary element method 

    Duffo Ubeda, Núria; Vall-Llossera Ferran, Mercedes Magdalena; Camps Carmona, Adriano José; Corbella Sanahuja, Ignasi; Bará Temes, Francisco Javier; Torres Torres, Francisco (2000)

  • Method of moments applied to the analysis of rough surfaces modelled by fractals 

    Vall-Llossera Ferran, Mercedes Magdalena; Duffo Ubeda, Núria; Camps Carmona, Adriano José; Corbella Sanahuja, Ignasi; Bará Temes, Francisco Javier; Torres Torres, Francisco (2000)
    Text en actes de congrés
    Accés obert
    The Scattering and Emissivity of rough surfaces involve solutions to non-linear differential equations. Different approaches have been used in the literature to obtain approximate solutions under some hypothesis. For example ...
