Abstract

The Microwave Radiometer (MWR), on board of the SAC-D/Aquarius satellite, is a Dicke radiometer, operating at 23.8 and 36.5 GHz that was developed by Argentine Space Agency, CoNAE. Since the first earth surface TB images, there has been an anomalous effect when observing strong contrast radiometric scenes, such as land/water crossings. This effect is present in all push-broom beams and results in a 'smearing' of TB observations near high contrast areas. This paper presents the initial findings on this MWR brightness temperature anomaly that is best described as a coupling of sequential MWR feed horn measurements. In the present work, an empirical approach is used to mitigate this anomalous effect. © 2012 IEEE.
