    • Sea surface emissivity observations at L-band: first results of the Wind and Salinity Experiment WISE 2000 

      Camps Carmona, Adriano José; Font Ferré, Jordi; Etcheto, J; Caselles Costa, Vicent; Weill, A; Corbella Sanahuja, Ignasi; Vall-Llossera Ferran, Mercedes Magdalena; Duffo Ubeda, Núria; Torres Torres, Francisco; Villarino Villarino, Ramón; Enrique, L; Julia, A; Gabarro, C; Boutin, J; Rubio, E; Reising, S; Wursteisen, P.; Berger, M.; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2002-10)
      Article
      Accés obert
      Sea surface salinity can be measured by passive microwave remote sensing at L-band. In May 1999, the European Space Agency (ESA) selected the Soil Moisture and Ocean Salinity (SMOS) Earth Explorer Opportunity Mission to ...
    • The Emissivity Of Foam-Covered Water Surface At L-Band: Theoretical Modeling And Experimental Results From The FROG 2003 Field Experiment 

      Camps Carmona, Adriano José; Vall-Llossera Ferran, Mercedes Magdalena; Villarino Villarino, Ramón; Reul, Nicolas; Chapron, Bertrand; Corbella Sanahuja, Ignasi; Duffo Ubeda, Núria; Torres Torres, Francisco; Miranda Mendoza, Jorge José; Sabia, Roberto; Monerris Belda, Alessandra; Rodríguez Sánchez, Rubén (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2005-05-31)
      Article
      Accés obert
      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: a concept for robust beamforming and high resolution DOA tracking 

      Pérez Neira, Ana Isabel; Villarino Villarino, Ramón; Lagunas Hernandez, Miguel A. (IEEE Press, 2000)
      Text en actes de congrés
      Accés obert
      Motivated by the objective of finding a reduced complexity implementation of the EM (estimate and maximize) algorithm, the authors move the concept of alternating projection (AP), reported Ziskind and Wax (1988), to a ...

      Text en actes de congrés
      Accés obert
      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)
      Text en actes de congrés
      Accés obert
      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 ...
