摘　　要：该文设计和实现了基于高性能机群的环境一号C卫星SAR图像全分辨率快视实时处理系统,该系统对环境一号C卫星2012年12月9日首次开机获取的SAR遥感数据进行了快视图像处理。结果表明:该快视处理系统完全满足SAR图像全分辨率快视实时处理能力。该系统是我国首次实现星载SAR图像全分辨率快视实时处理的业务运行系统。This study is concerned with the design and implementation of a real-time processing system of full resolution quick-look image of H J-1 environmental satellite C SAR based on high-performance clusters. The system processes the first quick-look SAR image on December 9, 2012. The results show that the design and implementation of the quick-look processing system satisfies the real-time SAR image processing performance requirements at full resolution. Moreover, this system is the first real-time business system of full-resolution quick-look spaceborne SAR images in China .
