    • A calibration method for fully polarimetric microwave radiometers 

      Lahtinen, J..; Gasiewski, A.J.; Klein, M.; Corbella Sanahuja, Ignasi (IEEE Press. Institute of Electrical and Electronics Engineers, 2003-03)
      Article
      Accés obert
      A technique for absolute end-to-end calibration of a fully polarimetric microwave radiometer is presented. The technique is based on the tripolarimetric calibration technique of Gasiewski and Kunkee, but is extended to ...

    • Compensation of elevation angle variations in polarimetric brightness temperature measurements from airborne microwave radiometers 

      Corbella Sanahuja, Ignasi; Gasiewski, A.J.; Klein, Marian; Piepmeier, Jeffrey R. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2001-01-31)
      Article
      Accés obert
      This paper presents a method for compensating the elevation angle fluctuations occurring in airborne radiometry due to aircraft roll and pitch. The correction is based on a radiative transfer model, and is demonstrated by ...

    • On Board Accurate Calibration of Dual-Channel Radiometers Using Internal and External References 

      Corbella Sanahuja, Ignasi; Gasiewski, A.J.; Klein, Marian; Leuski, Vladimir; Francavilla, A. J.; Piepmeier, Jeffrey R. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2002-07-31)
      Article
      Accés obert
      This paper presents a method for combining internal noise injection and external reference standard looks to accurately calibrate an airborne dual-channel radiometer. The method allows real-time estimation of the correct ...
