Abstract :
The Corbella´s revision of the fundamental equation of the interferometric aperture synthesis radiometry is verified using airborne and spaceborne data. This experimental verification uses the measurements of the airborne instrument HUT-2D from the Aalto University (Helsinki), and the unique spaceborne microwave imaging radiometer by aperture synthesis (MIRAS) from the ESA´s Soil Moisture and Ocean Salinity (SMOS) mission. The data acquired with those sensors support the Corbella´s revision of the visibility function. The revised function predicts that visibilities depend on the contrast between the target´s brightness temperature and the backward noise of the receivers emitted through the antennas.
