SAR地面数据处理站的构建

The Construction of SAR Data Processing Ground Station

提出了一种基于浏览器/服务器结构的高性能SAR地面数据处理站的构建模式,采用CGI技术将用户交互界面与图像计算功能相分离,以高性能工作站作为计算服务器对SAR图像进行处理,大大降低了对客户终端的性能要求,充分利用了服务器的强大计算能力和内存容量及客户浏览器的灵活访问方式,自然地实现了SAR图像数据管理、情报处理和情报分发功能。该模式已在实际SAR地面系统中得到应用,使SAR图像的处理速度得到显著提高。

The model of a highly efficient SAR data processing ground station, based on B/S（browser/ server） structure, is proposed in this paper. By means of separating image processing from custom mutual interfaces using CGI technique, and best using of the powerful computing ability of server and the flexible visit manner of the client, the high-powered workstation is used as the computing server in this ground station. This reduces the performance requirement of the client terminal. Naturally, SAR image data management, information processing and information distribution are realized and have been used in a particular SAR ground system. The SAR image processing speed has been improved observably by using this ground station.
