Abstract

Narrow-band interference (NBI) is a known issue in radar remote sensing. For synthetic aperture radar (SAR) imaging process, NBI would cause severe degradation of image quality, and poses a hindrance to image interpretation. In this paper, three advanced techniques for NBI suppression, i.e., the Eigensubspace projection, the independent component analysis (ICA) and the independent subspace analysis (ISA) are discussed. A comparison of these techniques is provided. Experimental results indicate the effectiveness of these methods.
