    • Contribution to the application of near ground L-band radiometry 

      Burnham, Colin Jeffrey (Universitat Politècnica de Catalunya, 2019-07-16)
      Projecte Final de Màster Oficial
      Accés obert
      ARIEL is an L-band radiometer adapted from Earth Observation satellite technology for use in terrestrial, near to ground surveys of moisture. The key technical benefits are compact size, lightweight, mobility and high pixel ...

    • Design of a deployable helix antenna at L-Band for a 1-Unit CubeSat: from theoretical analysis to flight model results

      Article
      Accés obert
      In May 1999, the European Space Agency (ESA) selected the Earth Explorer Opportunity Soil Moisture and Ocean Salinity (SMOS) mission to obtain global and frequent soil moisture and ocean salinity maps. SMOS' single payload ...

    • Soil moisture retrieval using an airborne L-Band Radiometer 

      Duperrier, Arnaud (Universitat Politècnica de Catalunya, 2009-02-27)
      Projecte/Treball Final de Carrera
      Accés obert
      This work project will be divided in 5 chapters. Firstly, chapter two reviews the basics of radiometry, emission theory and types of radiometer. Chapter three covers the avionic system in place aboard the platform, ...

    • Study of radio frequency interference effects on radiometry bands in urban environments 

      Forte Veliz, Giuseppe Francesco; Camps Carmona, Adriano José; Tarongí Bauzá, José Miguel; 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
      Microwave radiometers are very accurate passive sensors that have been successfully used in Earth remote sensing during the last decades. Microwave radiometers measure thermal noise, therefore any other signal (radio-frequency ...

    • 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)
