Abstract

Radio Frequency Interference (RFI) will influence the interferometric image easier than the amplitude image in the Very High Frequency/Ultra High Frequency (VHF/UHF) Synthetic Aperture Radar (SAR). In this paper, a simpler detector with binary hypothesis is constructed with the discussion of the thresholds. Based on this, a new interference suppression method based on azimuth-time range-spectrum domain of along-track interferometric image is proposed. The approach is effective for ground moving target detection in real-time processing and its performance is testified by simulation data.
