制导仿真数据仓库研究

Research on the Guidance Simulation Data Warehouse

制导仿真试验和飞行试验都会产生许多数据,数据逐渐累积形成海量数据,针对分析需求对数据进行有效管理,制导仿真数据的管理成为当前国内仿真界面临的难题。鉴于数据仓库管理海量数据、面向分析、支持决策的特性,将数据仓库技术引入到制导仿真数据管理领域,设计出了制导仿真数据仓库的体系架构。针对制导仿真所涉及数据的特点,对制导仿真数据仓库构建过程中先对数据预处理进行研究,提出了制导仿真数据仓库的数据预处理模型,进行仿真证明,模型能有效指导制导仿真数据仓库构的数据预处理工作,可为有关人员快速有效地获取所需数据。

Both guidance simulation experiment and flight test can produce many data,and the data amount may become very large after a long time.Managing these data based on the analysis requirements from the simulation analyzer has great significance.And how to manage the data related to guidance simulation is a problem to be resolved for the domestic simulation realm.Based on the character of data warehouse that managing a large amount of data,focusing on analyses and supportting decision-making,the data warehouse was introduced into the data management field of guidance simulation,and the system framework for the guidance simulation data warehouse（GSDW） was designed.With consideration of the data character of the guidance simulation system,some research has been done on data preprocessing which is a technical difficulty during the construction of the GSDW,and a kind of data preprocessing model for the GSDW was put forward.This model can supervise the data preprocessing related to the building of the GSDW effectively.
