Abstract
Polarization changes for off-axis rays, while a minor effect for narrow-beam antennas, become a significant issue for wide-beam antennas required by synthetic aperture radiometry. This note provides the angle-dependent relationship between upwelling fields and collected signals; results are illustrated by the case of the Surface Moisture and Ocean Salinity (SMOS) mission.
