Speckle Reduction for High Resolution One Look Spaceborne SAR Images

LI Chun sheng,YAN Ying,CHEN Jie,HUANG Yan,ZHOU Yin qing(Dept.of Electronic Engineering,Beijing University of Aeronautics and Astronautics,Beijing 100083,China)  
In this paper,a method is developed for speckle reduction of high resolution one look spaceborne synthetic aperture radar images.This method,named TDRGMAP,makes high spatial resolution and high radiometric resolution one look SAR image possible by means of smoothing speckle with MAP filter,removing bias for one look image,using edge and line detector,and preserving detected point targets.TDRGMAP is discussed in detail,and its efficiency is demonstrated with simulated spaceborne SAR image.
