SAR图像斑点噪声滤除研究文献综述

Literature Review of the SAR Image Speckle

SAR图像中斑点噪声的存在会严重影响到其图像解译和后期处理,故对斑点噪声滤除的研究探讨一直是国际热点。近些年发展了许多SAR图像去噪的方法,文中对这些方法进行归纳总结,分析了其原理、优缺点及其适用范围,对下一步研究SAR噪声工作具有一定的指导意义。

The existence of SAR image speckle noise can seriously affect the SAR image interpretation and subsequent processing,so the research and investigation of smoothing speckle noise have been the international hot.In recent years,a lot of method about SAR image denoising had been developed,in the paper,the author summarizes these methods and analyzes the methods of the latest research status,advantages,disadvantages and applicable scope.It has a certain guiding significance on the next step of the SAR noise work.
