    The Global Navigation Satellite System Reflectometry (GNSS-R) concept was conceived as a means to densify radar altimeter measurements of the sea surface. Until now, the GNSS-R concept relied on open access to GNSS ...
  • Experimental study on the performance of RFI detection algorithms in microwave radiometry: Toward an optimum combined test 

    Forte Veliz, Giuseppe Francesco; Tarongí Bauzá, José Miguel; Depau, Veronica; Vall-Llossera Ferran, Mercedes Magdalena; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2013-10)
    Article

    This work presents the preliminary performance study of several RFI detection and mitigation algorithms applied to real data. The used algorithms include statistical analysis in the time and frequency domains and time and ...
  • Radio frequency interference in microwave radiometry: statistical analysis and study of techniques for detection and mitigation 

    Tarongí Bauzá, José Miguel (Universitat Politècnica de Catalunya, 2013-03-06)
    Doctoral thesis
    Open Access
    Microwave radiometry field has been increasing its performance with higher accuracy measurements, leading to a more presence in the remote sensing field. Several space-borne, air-borne and ground-based radiometers have ...
  • Review of GNSS-R instruments and tools developed at the Universitat Politecnica de Catalunya-Barcelona Tech 

    Camps Carmona, Adriano José; Marchán Hernández, Juan Fernando; Bosch Lluís, Xavier; Rodríguez Álvarez, Nereida; Ramos Pérez, Isaac; Valencia Domènech, Enric; Tarongí Bauzá, José Miguel; Hyuk, Park; Carreño Luengo, Hugo; Alonso Arroyo, Alberto; Pascual Biosca, Daniel; Onrubia Ibáñez, Raúl; Forte Veliz, Giuseppe Francesco; Querol Borràs, Jorge (2014)
    Conference lecture
    Restricted access - publisher's policy
    Reflectometry using Global Navigation Satellite System's signals of opportunity (GNSS-R) was originally conceived in the early 90s for mesoscale altimetry, and since then, many studies have shown its applicability to other ...
  • RFI mitigation in microwave radiometry using wavelets 

    Camps Carmona, Adriano José; Tarongí Bauzá, José Miguel (2009-09)
    Article
    Open Access
    The performance of microwave radiometers can be seriously degraded by the presence of radio-frequency interference (RFI). Spurious signals and harmonics from lower frequency bands, spread-spectrum signals overlapping the ...
  • Study of radio frequency interference effects on radiometry bands in urban environments 

    Forte Veliz, Giuseppe Francesco; Camps Carmona, Adriano José; Tarongí Bauzá, José Miguel; Vall-Llossera Ferran, Mercedes Magdalena (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    Conference report
