SAR成像质量指标评估软件系统的设计

Design of system of SAR image quality parameters assessment

合成孔径雷达(SAR,Synthetic Aperture Radar)是一种应用广泛的微波遥感成像雷达,能够全天时、全天候对地观测成像,并且图像有着高方位分辨率。SAR图像研究是遥感方向最为重要的前沿领域之一。目前没有一套专门的软件系统工具来对SAR成像进行指标的计算与测量,都是建立在通用的辅助工具如MATLAB上,计算效率低且不方便。文中设计了一种SAR成像的质量评估系统软件,该系统中包含一套比较完备的SAR成像质量指标,然后以这套指标为主要出发点,设计开发出SAR图像质量指标评价的软件。该软件以C/C++语言为基础,以OGRE和CEGUI等开源库为框架。该系统能够实现对数据文件的读取、图像的基本操作、图像和数据的质量指标测定、指标的测定和计算等,并且有着友好的人机交互功能。

Synthetic aperture radar is a kind ol microwave remote sensing imaging radar,it can achieveall-weather all-time earth observation and imaging. It can also generate high-resolution S A R image inboth range and azimuth dimensions. S A R image research is one ol the most important and frontier area insensing direction. Currently, there is no specialized software system tool to calculate the S A R imagequality parameters, we usually work with acommon support tools such as MATLAB ,and it isinconvenient. This paper designs a softwareol SAR image quality parameter assessment, it includes aserious ol important S A R image quality parameters,and the quality parameter is the starting point ol thesoftware. The soltware is based on C and C ＋ ＋ language,the open source library ol OGRE and CEGU Iare the lrame ol the soltware,with these it designs a kind ol practical soltware. The soltware has theability ol reading image and data liles, basic operation on image, the evaluation and calculation ol imageand data quality parameters. it has a lriendly interactive lunction.
