  • 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 ...
