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 obertSea 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 obertMotivated 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 ... -

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 obertThis 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 ... -
