摘要: The European Space Agency (ESA) successfully launched the Soil Moisture and Ocean Salinity (SMOS) mission in November 2, 2009. SMOS uses a new type of instrument, synthetic aperture radiometer named MIRAS that provides full-polarimetric multi-angular L-band brightness temperatures, from which regular global maps Sea Surface (SSS) (SM) are generated. Although operates restricted band (1400-1427 MHz), radio-frequency interference (RFI) appears imagery many areas world, it is an important issue to be addressed for quality SSS SM retrievals. impact on sinusoidal RFI source reviewed, problem illustrated with actual encountered by SMOS. Two detection mitigation algorithms developed (dual-polarization modes), performance second one has been quantitatively evaluated terms probability false alarm (using test scene), results presented
