    After more than four years of operation, the SMOS (Soil Moisture and Ocean Salinity) European Space Agency (ESA) mission [1] has proven to be highly useful for a variety of scientific applications related to soil moisture ...
  • Experimental demonstration of multi-band upstream in statistical OFDM-PONs and comparison with digital subcarrier assignment 

    Cano Valadéz, Iván Nicolás; Escayola Elias, Francisco Javier; Schindler, Philipp C.; Santos Blanco, M. Concepción; Polo Querol, Víctor; Leuthold, Juerg; Prat Gomà, Josep Joan (Institute of Electrical and Electronics Engineers (IEEE), 2014)

    A multiband subcarrier allocation scheme is demonstrated for the uplink in a statistical OFDM-PON. Performance achieved is similar to digital subcarrier allocation, with the significant advantage of a lower transmitter complexity.
  • Residual calibration error impact on SMOS SLL performance 

    Torres Torres, Francisco; Corbella Sanahuja, Ignasi; Durán Martínez, Israel; Lin, Wu; Duffo Ubeda, Núria; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2014)

    SMOS Side Lobe Level (SLL), which is caused by the limited coverage of the measured visibility samples in the frequency domain, is responsible for non-negligible radiometric errors at pixels placed close to large brightness ...
  • Una experiencia de evaluación continuada en Radiación y Propagación 

    Torres Torres, Francisco; Fabregas Canovas, Francisco Javier; López Martínez, Carlos; Corbella Sanahuja, Ignasi (Editorial Universitat Politècnica de València, 2014)

  • Equivalent circuits of planar filtering antennas fed by apertures 

    Kufa, Martin; Raida, Zbynek; Mateu Mateu, Jordi (2014)
    Conference report
    Restricted access - publisher's policy
    The paper is focused on a design of a three-element filtering patch antenna array using an equivalent-circuit approach. The array is requested to exhibit a prescribed frequency response of a realized gain which corresponds ...
  • RF monitoring of commercial vascular stents with dipole scattering resonances 

    Arauz Garofalo, Gianluca; López Domínguez, Víctor; Hernández Ferras, Joan Manel; Rodríguez Leor, Oriol; Bayés Genis, Antoni; Rius Casals, Juan Manuel; O'Callaghan Castellà, Juan Manuel; García Santiago, Antoni; Tejada Palacios, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2014)

    We have compared measurements and simulations of the microwave forward scattering of several commercial coronary stents. We immerse the stents in water to replicate the permittivity of biological tissues and find that their ...
  • Faraday rotation angle retrieval using SMOS radiometric data 

    Wu, Lin; Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Duffo Ubeda, Núria; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report

    SMOS radiometric data is used to derive Faraday rotation for a number of orbits combining several scenarios: land, ice and water. Results compare very well with the values theoretically predicted from available ionosphere ...
  • Advances in calibration of the SMOS zero-baseline radiometers 

    Colliander, Andreas; Chae, Chunsik; Dinnat, Emmanuel Philippe; Oliva, Roger; Kainulainen, Juha; Torres Torres, Francisco; Corbella Sanahuja, Ignasi; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report

    Over the course of the more than four-year mission several enhancements have been developed for the calibration of the zero-baseline radiometers of ESA's SMOS (Soil Moisture Ocean Salinity) mission. Here a particular ...
  • A novel reconstruction algorithm for the improvement of SMOS brightness temperatures 

    González Gambau, Veronica; Turiel, Antonio; Martinez, Justino; Olmedo, Edson; Corbella Sanahuja, Ignasi (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Restricted access - publisher's policy
    RFI (Radio Frequency Interference) sources, Sun signal and even land-sea transitions may generate large sidelobes that corrupt SMOS brightness temperature products and therefore, the quality of the soil moisture and sea ...
