Abstract

SAR(Synthetic Aperture Radar) is known to be vulnerable to interference signals coming from other communication devices or radar instruments and suffer from undesirable performance degradations. In this paper, a modified LMS adaptive filter is proposed that can be easily applied to the SAR images affected by the interference signals. We present a simulation results that proves to be effectiveness of the LMS algorithm for interference suppression while the SAR image quality is well preserved compared with the notch-filter case.
