N2 - Radio frequency interference (RFI) source localization is essential for providing valuable priori information for RFI mitigation. For synthetic aperture radar (SAR) system, existing RFI localization methods face the challenge of severe localization ambiguity. To deal with this deficiency, this paper studies the mapping relationship between the interferometric phase properties of RFI and the location. It establishes a localization framework with alternating constraints to achieve an unambiguous range and azimuth localization. Finally, the localization accuracy is validated in real dual-channel echo data combined with simulated RFI. Compared to existing localization methods, the proposed approach could achieve azimuth accuracy at the meter level and range accuracy at the kilometer level without ambiguities.
