  • A new calibration technique for interferometric radiometers 

    Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Camps Carmona, Adriano José; Bará Temes, Francisco Javier (1998)
    Conference report
    Open Access
    This paper presents a new method for receiver calibration of interferometric radiometers. It is based on the distributed noise injection mechanism and it consists of fully calibrating the baseline error terms of the central ...
  • Correlation denormalization in interferometric or polarametric radiometers: a unified approach 

    Colliander, Andreas; Torres Torres, Francisco; Corbella Sanahuja, Ignasi (IEEE, 2009-02)
    Article
    Open Access
    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 ...
  • Wide field of view microwave interferometric radiometer imaging 

    Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Duffo Ubeda, Núria; Durán Martínez, Israel; González Gambau, Verónica; Martín Neira, Manuel (Multidisciplinary Digital Publishing Institute (MDPI), 2019-03-02)
    Article
    Open Access
    In microwave interferometric radiometers with a large field of view, as for example the Microwave Imaging Radiometer with Aperture Synthesis (MIRAS) onboard the Soil Moisture and Ocean Salinity (SMOS) satellite, one of the ...
