摘要：

Synthetic aperture radar (SAR) shares its radio frequency with the other systems and thus, inevitably receives their signals. Such cross-talk, radio frequency interference (RFI) has been traditionally eliminated by spectrum filters. However, a latest L-band SAR, ALOS-2, receives frequency modulated wideband signals that cannot be detected by traditional spectrum filters. These RFIs have the same or wider bandwidth than SAR and thus, appears in SAR images. They also interrupt interferometric (InSAR) and polarimetric (PolSAR) analysis because it appears in every observations and in full-polarimetric mode images. We report the investigation results of the profiles of such RFI in Tokyo bay, Japan.
