摘　　要：分析了遥感业务化处理系统的现实需求,针对当前遥感业务化处理系统存在的不足,结合遥感业务化处理系统和遥感影像并行处理算法两方面研究的成果,提出了基于三级并行的遥感业务化处理系统设计方案,将数据并行、功能并行、任务并行融合到遥感业务化系统中,并在环境与灾害监测预报小卫星星座系统工程中得到应用,为环境减灾提供了快速的遥感处理支持。介绍了系统的体系结构,工作流程,重点研究了三级并行的实现方式,并借助产品实例对其性能进行了测试。结果表明,基于三级并行的遥感业务化处理系统设计方案能够有效的提高遥感业务化处理的效率。After analyzing the current requirements and deficiency of remote sensing regular system, remote sensing regular pro- cessing system based on tri-level parallel implementation is promoted, which integrates achievements in researches on remote sensing regular system and remote sensing image parallel processing algorithm. The system compromises data parallel, function parallel, and task parallel technologies, and is used in monitoring and pre-warning system project of environment and hazard for small Satellite constellation, and provides efficient remote sensing processing supports for environmental hazards decrease. The system＇s architecture and workflow are introduced while tri-level parallel implementation is specially focused on. Simultaneously, testing based on product example is presented, which shows that this design promotes the efficiency of remote sensing regular processing system.
