Abstract :
Synthetic aperture imaging radiometers (SAIR) are powerful instruments for high-resolution observation of the Earth surface at low microwave frequencies. This article deals with the impact of correlators and receivers failures on the reconstruction process which aims at inverting the interferometric data for retrieving the radiometric brightness temperature distribution of the scene under observation. Numerical simulations are carried out for the SMOS space mission, a project led by the European Space Agency and devoted to the remote sensing of soil moisture and ocean salinity from a low orbit platform.
