Calibration Consistency Tool for Interferometric Radiometers

This paper presents a method to check the consistency of the amplitude calibration in interferometric radiometers devoted to Earth observation This tool is based in the intrinsic properties of the internal calibration scheme and can be used to systematically assess in-orbit the quality of the amplitude calibration coefficients. This technique is illustrated taking into account the results of the validation and system performance tests recently undertaken by the MIRAS instrument, the single payload of the Soil Moisture and Ocean Salinity mission of the European Space Agency.
