结合边缘和线条检测

并加以点目标检测及保持

获得高空间分辨率和高辐射分辨率的SAR单视图像.本文详细阐述了TDRGMAP方法的机理和实现

最后利用仿真生成的星载SAR单视图像进行实验

证明了TDRGMAP方法的有效性.

Abstract

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.
