  • For Very High Frequency/Ultra High Frequency(VHF/UHF) Ultra-WideBand Synthetic Aperture Radar (UWB SAR) the Radio Frequency Interference(RFI) may degrade the SAR image. In this paper a method based on channel equalization is proposed to remove the RFI yet preserve SAR image quality. The effectiveness of the method is also verified with the real data from an airborne VHF/UHF UWB SAR.
