      This work analyzes the satellite cross-talk observed by the microwave interferometric reflectometer (MIR), a new global navigation satellite system (GNSS) reflectometer, during an airborne field campaign in Victoria and ...

    • The dual polarization GNSS-R interference pattern technique 

      Alonso Arroyo, Alberto; Camps Carmona, Adriano José; Monerris Belda, Sandra; Ruudiger, C.; Walker, Jeffrey; Forte Veliz, Giuseppe Francesco; Pascual Biosca, Daniel; Hyuk, Park; Onrubia Ibáñez, Raúl (Institute of Electrical and Electronics Engineers (IEEE), 2014)

      Accés restringit per política de l'editorial
      Since 2003 several field experiments using Global Navigation Satellite Systems (GNSS)-Reflectometry (GNSS-R) have demonstrated the feasibility of retrieving Soil Moisture (SM) from GNSS-R observations. Different techniques ...

    • The light airborne reflectometer for GNSS-R observations (LARGO) instrument: initial results from airborne and Rover field campaigns 

      Alonso Arroyo, Alberto; Camps Carmona, Adriano José; Monerris Belda, Sandra; Rudiger, Christoph; Walker, Jeffrey; Forte Veliz, Giuseppe Francesco; Pascual Biosca, Daniel; Hyuk, Park; Onrubia Ibáñez, Raúl (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Global Navigation Satellite Systems (GNSS)-Reflectometry (GNSS-R) has proved to be a useful technique for the estimation of Soil Moisture (SM). In the past 10 years, different techniques such as the Interference Pattern ...

    • 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)

      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 ...

    • 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 ...
