      Accés restringit per política de l'editorial
      Over the course of the more than four-year mission several enhancements have been developed for the calibration of the zero-baseline radiometers of ESA's SMOS (Soil Moisture Ocean Salinity) mission. Here a particular ...

    • Analysis of Correlation and Total Power Radiometer Front-Ends Using Noise Waves 

      Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Camps Carmona, Adriano José; Duffo Ubeda, Núria; Vall-Llossera Ferran, Mercedes Magdalena; Rautiainen, Kimmo; Martín Neira, Manuel; Colliander, Andreas (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2005-11-30)
      Article
      Accés obert
      A complete and systematic noise analysis of radiometer front-ends, including both total power and correlation measurements, is presented. The procedure uses the concepts of noise waves and S-parameters, widely used in ...

    • Correlation denormalization in interferometric or polarametric radiometers: a unified approach 

      Colliander, Andreas; Torres Torres, Francisco; Corbella Sanahuja, Ignasi (IEEE, 2009-02)
      Article
      Accés obert
      This paper presents a general analysis of correlation measurements in an interferometer or a radiometer based on noise injection and/or switching and measurement of normalized correlations (e.g., imaging synthetic aperture ...

    • MIRAS End-to-End Calibration: Application to SMOS L1 Processor 

      Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Camps Carmona, Adriano José; Colliander, Andreas; Martín Neira, Manuel; Ribó Vedrilla, Serni; Rautiainen, Kimmo; Duffo Ubeda, Núria; Vall-Llossera Ferran, Mercedes Magdalena (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2005-05-31)
      Article
      Accés obert
      End-to-end calibration of the Microwave Imaging Radiometer by Aperture Synthesis (MIRAS) radiometer refers to processing the measured raw data up to dual-polarization brightness temperature maps over the earth's surface, ...
