    • Dual-polarization GNSS-R interference pattern technique for soil moisture mapping 

      Alonso Arroyo, Alberto; Camps Carmona, Adriano José; Aguasca Solé, Alberto; Forte Veliz, Giuseppe Francesco; Monerris Belda, Alessandra; Rudiger, Christoph; Walker, Jeffrey; Hyuk, Park; Pascual Biosca, Daniel; Onrubia Ibáñez, Raúl (2014-05-01)
      Article
      Restricted access - publisher's policy
      The interference pattern technique (IPT) consists of the coherent addition of the direct and reflected global navigation satellite systems (GNSS) signals in the receiving antenna. The detected power oscillates (fading), ...

    • 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 ...

    • On the correlation between GNSS-R reflectivity and L-band microwave radiometry 

      Alonso Arroyo, Alberto; Camps Carmona, Adriano José; Monerris Belda, Sandra; Rudiger, Christoph; Walker, Jeffrey; Onrubia Ibáñez, Raúl; Querol Borràs, Jorge; Hyuk, Park; Pascual Biosca, Daniel (Institute of Electrical and Electronics Engineers (IEEE), 2016-12)
      Article
      Open Access
      This work compares microwave radiometry and global navigation satellite systems-reflectometry (GNSS-R) observations using data gathered from airborne flights conducted for three different soil moisture conditions. Two ...

    • Predicting the extent of wildfires using remotely sensed soil moisture and temperature trends 

      Chaparro Danon, David; Vall-Llossera Ferran, Mercedes Magdalena; Piles Guillem, Maria; Camps Carmona, Adriano José; Rudiger, Christoph; Riera Tatche, Ramón (Institute of Electrical and Electronics Engineers (IEEE), 2016-06-01)
      Article
      Open Access
      Recent climate trends evidence a rise of temperatures and an increase in the duration and intensity of droughts which is in turn leading to the occurrence of larger wildfires, which threaten the environment as well as human ...

    • Preliminary end- to-end results of the MIR instrument: the microwave interferometric reflectometer 

      Onrubia Ibáñez, Raúl; Pascual, D.; Querol Borràs, Jorge; Hyuk, Park; Camps Carmona, Adriano José; Rudiger, Christoph; Walker, Jeffrey (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference report
      Restricted access - publisher's policy
      Global Navigation Satellite Systems - Reflectometry (GNSS-R) has shown his potential for remote sensing. Since new wider band signals are being broadcasted, and new systems are becoming available, a performance comparison ...

    • Satellite cross-talk impact analysis in airborne interferometric global navigation satellite system-reflectometry with the microwave interferometric reflectometer 

      Onrubia Ibáñez, Raúl; Pascual Biosca, Daniel; Hyuk, Park; Camps Carmona, Adriano José; Rudiger, Christoph; Walker, Jeffrey; Monerris Belda, Alessandra (Multidisciplinary Digital Publishing Institute (MDPI), 2019-05-01)
      Article
      Open Access
      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 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)

      Restricted access - publisher's policy
      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 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 ...
