    Article
    Open Access
    Global navigation satellite system reflectometry (GNSS-R) is a group of techniques that uses satellite navigation signals as signals of opportunity for remote sensing applications. In GNSS-R, large amounts of data are ...
  • Untangling the incoherent and coherent scattering components in GNSS-R and novel applications 

    Muñoz Martin, Joan Francesc; Onrubia Ibáñez, Raúl; Pascual Biosca, Daniel; Hyuk, Park; Camps Carmona, Adriano José; Rudiger, Christoph; Walker, Jeffrey; Monerris Belda, Alessandra (Multidisciplinary Digital Publishing Institute (MDPI), 2020-04-09)
    Article
    Open Access
    As opposed to monostatic radars where incoherent backscattering dominates, in bistatic radars, such as Global Navigation Satellite Systems Reflectometry (GNSS-R), the forward scattered signals exhibit both an incoherent ...
  • Experimental evidence of swell signatures in airborne L5/E5a GNSS-reflectometry 

    Muñoz Martin, Joan Francesc; Onrubia Ibáñez, Raúl; Pascual Biosca, Daniel; Hyuk, Park; Camps Carmona, Adriano José; Rudiger, Christoph; Walker, Jeffrey; Monerris Belda, Alessandra (Multidisciplinary Digital Publishing Institute (MDPI), 2020-05-29)
    Article
    Open Access
    As compared to GPS L1C/A signals, L5/E5a Global Navigation Satellite System-Reflectometry (GNSS-R) improves the spatial resolution due to the narrower auto-correlation function. Furthermore, the larger transmitted power ...
