      In the frame of an SMOS follow-on operational mission, a new instrument design is being developed based on the lessons learned from MIRAS, the SMOS payload. To reduce hardware complexity and mass, digital In-phase Quadrature ...
    • 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 ...
