On-Ground RFI Mitigation for Spaceborne Multichannel SAR Systems Using Auxiliary Beams
2022
IEEE Transactions on Geoscience and Remote Sensing
Radio frequency interference (RFI) is becoming a major concern for future synthetic aperture radar (SAR) missions due to the increased user demand for frequency occupation in a number of applications. Each occurrence of interference introduces artifacts in the radar imagery, biasing the measurements and leading to erroneous results. In addition to conventional techniques, the use of multichannel SAR for RFI mitigation has been proposed, because its digital beamforming (DBF) capability allows
