Abstract

Synthetic Aperture Radar is a coherent system. The echo phases of different scatters are different in the same resolution unit. The coherent superposition of the echo phases results in speckle noise of SAR images. Coherent speckle noise seriously affects SAR image understanding and feature extraction. The purpose of speckle filtering in SAR images is to preserve the texture features and scattering characteristics of the edges of the objects and to minimize the influence of speckle noise.
