Assessment on linearity errors in detectors for interferometric radiometers

The performance of the power detectors used to denormalize the digital correlations in interferometric radiometers is degraded due to the non-linear behavior of the diode response. This work presents a comprehensive analysis of the impact of detector non-linearity and related correction techniques in the performance of the MIRAS (Microwave Imaging Radiometer with Aperture Synthesis) instrument [1], which is the single payload of the European Space Agency (ESA) Soil Moisture and ocean Salinity (SMOS) missionPeer ReviewedPostprint (published version
