【摘要】 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。更多还原

【Abstract】 Synthetic aperture radar is a kind of microwave remote sensing imaging radar,it can achieve all-weather all-time earth observation and imaging. It can also generate high-resolution SAR image in both range and azimuth dimensions. SAR image research is one of the most important and frontier area in sensing direction. Currently,there is no specialized software system tool to calculate the SAR image quality parameters, we usually work with a common support tools such as MATLAB, and it is inconvenient. This paper designs a software of SAR image quality parameter assessment,it includes a serious of important SAR image quality parameters,and the quality parameter is the starting point of the software. The software is based on C and C + + language,the open source library of OGRE and CEGUI are the frame of the software,with these it designs a kind of practical software. The software has the ability of reading image and data files,basic operation on image,the evaluation and calculation of image and data quality parameters. it has a friendly interactive function.更多还原
