Recent synthetic aperture radar (SAR) has become applying a multi-receiver system to achieve, for example, along track interferometry (ATI) and/or digital beam forming (DBF) for wide observation swath. In this paper, we propose a novel radio frequency interference (RFI) detection method especially for multi-receiver SAR systems. We assumed that RFI signals have more similarity than the summation of radar echoes among multiple receivers. Based on this idea, we performed an interferometric analysis for the SAR raw data in both time and frequency domain and, removed the signals which marked extremely high correlation. We report experimental results with full-polarimetric F-SAR dataset.
