复杂网络环境下天基信息获取体系能力评价

Capability Assessment of Space Information Acquisition System-of-Systems Based on Cyber Environment

在航天装备日益体系化、网络化的大环境下,天基信息获取能力不但受到任务航天器平台与载荷能力的影响,也越来越受到天基信息获取网络特性和网络环境的制约。在此背景下,初步构建了天基信息获取网络的能力指标体系,引入了网络环境对于信息获取体系的影响,提出了指标的算法与聚合方法,进一步构建并开展了仿真实验,检验了体系能力的变化,并提出了下一步的研究方向。这种评价方法具有典型性,对于天基信息网络中的其他类型网络的能力评价也可提供借鉴。

With the trends of systematization and networking of space equipment,the space-based information acquisition ability is not only affected by platform and the load capacity of the mission spacecraft,but also more and more affected by the characteristics and the cyber-space environment of space-based information acquisition network.In this context,we constructed the capability metrics of the space-based information acquisition network,introduced the influence of the network environment on the information acquisition system,put forward the algorithm and the aggregation method of metrics,and further built and carried out the simulation experiments,test the system capacity changes and put forward the direction of research in future.The approach to implement capability assessment is typical to provide references to other satellites sub-networks assessment in the space-borne information network.
