Ground processing RFI mitigation strategy for BIOMASS: A feasibility study

BIOMASS mission [1] was selected as the 7th Earth Explorer Mission within the frame of the ESA Earth Observation Envelope Programme. Being the BIOMASS instrument a P-band Synthetic Aperture Radar (SAR) and being that frequency bandwidth already in use by different services, the BIOMASS acquisitions are expected to be occasionally affected by Radio Frequency Interference (RFI). In the framework of a comprehensive strategy for the BIOMASS mission to cope with the interference signals, in addition to design choices at both mission and instrument level, in this paper it is presented a study aimed at verifying the feasibility of an on-ground processing approach to mitigate the quality degradation on BIOMASS Level1 data due to RFI.
