      Restricted access - publisher's policy
      This work describes a novel dual-band Global Navigation Satellite Systems Reflectometer (GNSS-R) that uses the P(Y) and C/A signals scattered over the sea surface to perform highly precise altimetric measurements. The ...
    • GNSS-R derived centimetric sea topography: an airborne experiment demonstration 

      Carreño Luengo, Hugo; Hyuk, Park; Camps Carmona, Adriano José; Fabra Cervellera, Fran; Rius Jordán, Antonio (2013-06)
      Article
      Restricted access - publisher's policy
      The results of two airborne experiments performed to test the precision and the relative accuracy of the conventional Global Navigation Satellite Systems Reflectometry (GNSS-R) technique employing only the C/A code are ...
    • Impact of the elevation angle in the coherence time as a function of the sea wave height 

      Martín Alemany, Francisco; Camps Carmona, Adriano José; Martín-Neira, Manuel; d'Addio, Salvatore; Fabra Cervellera, Fran; Rius Jordán, Antonio; Hyuk, Park (2015)
      Conference lecture
      Restricted access - publisher's policy
      For a given geometry, the coherence time of a GNSS-R waveform can be initially related to the significant wave height.However, when the coherence time is analyzed, several issues shall be considered, such as the geometry ...
    • Optimization and performance analysis of interferometric GNSS-R altimeters: application to the PARIS IoD mission 

      Camps Carmona, Adriano José; Hyuk, Park; Valencia Domènech, Enric; Pascual Biosca, Daniel; Martín Alemany, Francisco; Rius Jordán, Antonio; Ribó Vedrilla, Serni; Benito, Javier; Andres-Beivide, Ana; Saameno, Paula; Staton, Gavin; Martín Neira, Manuel; D'Addio, Salvatore; Willemsen, Philip (2014-05-01)
      Article

      Reflectometry using Global Navigation Satellite System's signals (GNSS-R) of opportunity was originally conceived in the early 1990 s for mesoscale altimetry, and since then, many studies have shown its applicability to ...
    • Significant wave height retrieval based on the effective number of incoherent averages 

      Martín Alemany, Francisco; Camps Carmona, Adriano José; Martín-Neira, Manuel; d'Addio, Salvatore; Fabra, Fran; Rius Jordán, Antonio; Hyuk, Park (2015)
      Conference lecture
      Restricted access - publisher's policy
      The effectiveness of incoherent averaging depends on the level of correlation between consecutive waveforms, which can vary with the geometry and with the sea state conditions. In addition it is also dependent on the ...
    • Typhoon observations using the interferometric GNSS-R technique 

      Martín Alemany, Francisco; Camps Carmona, Adriano José; Hyuk, Park; Fabra Cervellera, Fran; Rius Jordán, Antonio; Martín Neira, Manuel; d'Addio, Salvatore; Li, Weiqiang; Yang, Dongkai (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Conference report
      Restricted access - publisher's policy
      Typhoon motoring using Global Navigation Satellite System (GNSS) signals is a new application of the GNSS-R technique, with increasing interest in the last years. Examples of that can be the CYGNSS (Cyclone Global Navigation ...
