    Capability for sea surface salinity observation was an important gap in ocean remote sensing in the last few decades of the 20th century. New technological developments during the 1990s at the European Space Agency led to ...
  • L-Band Sea Surface Emissivity: Preliminary Results Of The WISE-2000 Campaign And Its Application To Salinity Retrieval In the SMOS Mission 

    Camps Carmona, Adriano José; Corbella Sanahuja, Ignasi; Vall-Llossera Ferran, Mercedes Magdalena; Duffo Ubeda, Núria; Torres Torres, Francisco; Villarino Villarino, Ramón; Enrique, L.; Julbé, F.; Font, Jordi; Julià, A.; Gabarró Prats, Carolina; Etcheto, Jacqueline; Boutin, Jacqueline; Weill, Alain; Caselles, Vicente; Rubio, Eva; Wursteisen, Patrick (2003-06-30)
    Article
    Open Access
    Soil moisture and ocean salinity at surface level can be measured by passive microwave remote sensing at L-band. To provide global coverage data of soil moisture and ocean salinity with three-day revisit time, the Earth ...
  • The emissivity of foam-covered water surface at L-band: theoretical modeling and experimental results from the FROG 2003 field experiment 

    Rodríguez, R; Monerris Belda, Alessandra; Sabia, Roberto; Miranda Mendoza, Jorge José; Camps Carmona, Adriano José; Vall-Llossera Ferran, Mercedes Magdalena; Villarino Villarino, Ramón; Reul, N; Chapron, B; Corbella Sanahuja, Ignasi; Duffo Ubeda, Núria; Torres Torres, Francisco (IEEE Press. Institute of Electrical and Electronics Engineers, 2005-05)
    Article
    Open Access
    Sea surface salinity can be measured by microwave radiometry at L-band (1400–1427 MHz). This frequency is a compromise between sensitivity to the salinity, small atmospheric perturbation, and reasonable pixel resolution. ...

  • The RCap: an architecture for robust beamforming and high resolution DOA tracking 

    Pérez Neira, Ana Isabel; Villarino Villarino, Ramón; Lagunas Hernandez, Miguel A. (2000)
    Conference report
    Open Access
    Motivated by the objective of finding a reduced complexity implementation of the EM (Estimate and Maximize) algorithm, the authors move the concept of altemating projection (AP),re ported in 1988 by I. Ziskind and ...
  • Tunable dual-band filters based on capacitive-loaded stepped-impedance resonators 

    Girbau Sala, David; Lázaro Guillén, Antoni; Pérez, A.; Martínez, Ester; Pradell i Cara, Lluís; Villarino Villarino, Ramón (2009)
    Conference report
    Open Access
    This paper proposes the design of tunable dual-band filters for multi-band multi-standard systems. The main objective is to provide frequency tunability in the second band while maintaining the first band fixed. To this ...
