摘　　要：基于天绘二号微波测绘卫星的总体设计和地面应用系统的建设发展,以卫星影像成果数据的存储、管理和备份恢复提取为目的,研究并设计了数据存储管理分系统。首先着眼于各类数据的存储、管理和维护需求进行分系统的功能子系统设计;再以功能设计为基础,进行体系架构、工作流程和接口关系等软件设计;然后从存储能力、归档能力和元数据索引等方面进行分系统的性能指标设计;最后从实际运行状况方面分析了分系统的整体应用性能。结果表明,该分系统的设计切实可行。Based on the overall design of TH-2 microwave surveying and mapping satellite and the development of its ground application sys-tem,aiming at the storage,management and recovery of satellite image result data,we studied and designed a data storage management subsys-tem.Firstly,we designed functional subsystems according to the demands of storage,management and maintenance.Then,we designed the archi-tecture,workflow and interface relation based on functional design,and designed the performance indexes of storage,archive and metadata index retrieve.Finally,we analyzed the overall application performances based on the actual running status,which confirmed that the design of subsys-tem was feasible.
