A Spaceborne SAR RFI Suppression Method Based on an Adaptive Subband-Forming Technology
Radio frequency interference (RFI) severely degrades the quality of spaceborne synthetic aperture radar (SAR) images. The most current methods usually mitigate interference in only a single domain, such as notch filtering (NF) in the frequency domain, beamforming (BF) in the spatial domain, or low-rank and sparse metho...
