The European Space Agency’s Soil Moisture and
Ocean Salinity (SMOS) mission will be the first one using two-dimensional
aperture synthesis radiometry for earth observation.
This study presents the formulation that relates instrument observables
and brightness temperature maps including cross-polar
antenna voltage patterns, which may be also different from element
to element. Finally, the radiometric accuracy degradation if
cross-polar patterns are neglected in the image reconstruction is
