    • Untangling the GNSS-R coherent and incoherent components: Experimental evidences over the ocean 

      Muñoz Martin, Joan Francesc; Onrubia Ibáñez, Raul; Pascual Biosca, Daniel; Hyuk, Park; Camps Carmona, Adriano José; Rudiger, Christoph; Walker, Jeffrey; Monerris Belda, Alessandra (2020)
      Text en actes de congrés
      Accés obert
      Global Navigation Satellite Systems Reflected (GNSS-R) signals exhibit an incoherent and a coherent components [1], [2]. Current models assume that one or the other are dominant, and the calibration, and geophysical parameter ...

    • 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
      Accés obert
      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 ...

    • Validation and experimental tests of the PAU-synthetic aperture radiometer 

      Ramos Pérez, Isaac; Forte Veliz, Giuseppe Francesco; Camps Carmona, Adriano José; Bosch Lluís, Xavier; Rodríguez Álvarez, Nereida; Valencia Domènech, Enric; Hyuk, Park; Vall-Llossera Ferran, Mercedes Magdalena (Institute of Electrical and Electronics Engineers (IEEE), 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper presents calibration and the radiometric performance of the Passive Advanced Unit Synthetic Aperture (PAU-SA) in order to verify the instrument's characterization.

    • Vegetation canopy height retrieval using L1 and L5 airborne GNSS-R 

      Muñoz Martínez, Francisco José; Pascual Biosca, Daniel; Onrubia Ibáñez, Raúl; Hyuk, Park; Camps Carmona, Adriano José; Rudiger, Christoph; Walker, Jeffrey; Monerris Belda, Alessandra (Institute of Electrical and Electronics Engineers (IEEE), 2021-11-29)
      Article
      Accés obert
      Vegetation canopy height (CH) is one of the important remote-sensing parameters related to forests’ structure, and it can be related to the biomass and the carbon stock. Global navigation satellite system-reflectometry ...

    • Vegetation water content estimation using GNSS measurements 

      Rodríguez Álvarez, Nereida; Bosch Lluís, Xavier; Camps Carmona, Adriano José; Ramos Pérez, Isaac; Valencia Domènech, Enric; Hyuk, Park; Vall-Llossera Ferran, Mercedes Magdalena (2012-03)
      Article
      Accés restringit per política de l'editorial
      Global Navigation Satellite Systems (GNSS) opportunity signals reflected at or near the Earth's surface have already shown their potential to perform retrievals of a number of geophysical parameters. Radio occultations ...

    • Wind direction signatures in GNSS-R observables from space 

      Guan, Dongliang; Hyuk, Park; Camps Carmona, Adriano José; Wang, Yong; Onrubia Ibáñez, Raúl; Querol Borràs, Jorge; Pascual Biosca, Daniel (2018-01-29)
      Article

    • Wind speed maping from the ISS using GNSS-R? A simulation study 

      Camps Carmona, Adriano José; Hyuk, Park; Alonso Arroyo, Alberto (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Reflectometry using Global Navigation Satellite System's signals of opportunity (GNSS-R) was originally conceived for mesoscale altimetry, but it can be applied to sea state determination (i.e. wind speed), among many other ...
