      GNSS-R techniques are currently being studied to remotely sense a number of geophysical parameters over different types of surfaces [1-6]. The Interference Pattern Technique (IPT) is based on the measurement of the ...

    • Study of maize plants effects in the retrieval of soil moisture using the interefence Ppttern GNSS-R technique 

      Rodríguez Álvarez, Nereida; Bosch Lluís, Xavier; Acevo Herrera, René; Aguasca Solé, Alberto; Camps Carmona, Adriano José; Vall-Llossera Ferran, Mercedes Magdalena; Ramos Pérez, Isaac; Valencia Domènech, Enric (2010)
      Comunicació de congrés
      Accés obert
      The use of Global Navigation Satellite Signals Reflections (GNSS-R) techniques to retrieve geophysical parameters from surfaces has been increased in the recent years. These techniques have resulted in suitable tools to ...

    • Using DDM asymmetry metrics for wind direction retrieval from GPS ocean-scattered signals in airborne experiments 

      Valencia Domènech, Enric; Zavorotny, Valery; Akos, Dennis M.; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2014-07)

      Accés restringit per política de l'editorial
      Reflectometry of signals of opportunity such as those emitted by a global navigation satellite system, known as GNSS-R, has been developed over the past years as a technique with great potential for ocean scatterometry, ...

    • 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)
