数据链作为C~4ISR系统的重要组成部分,承担了C~4ISR系统大部分信息流的分发任务,是C~4ISR系统夺取信息优势的重要保证,因此,如何分析和评价数据链的信息优势能力及其对C~4ISR系统整体信息优势的影响是数据链系统建设中一个重要的研究课题。在分析C~4ISR系统工作流程的基础上,给出了通信子域信息优势的评价指标定义及评估模型;并且重点分析了数据链的连通性、传输可靠性以及实时性对通信子域信息质量的影响,进而给出了数据链信息优势的数学描述和评估模型,并分析了其在整个C~4ISR系统信息优势中的影响。
As an important part of C ~ 4ISR system, data link undertakes most information flow distribution tasks in C ~ 4ISR system and is an important guarantee for C ~ 4ISR system to seize the information superiority. Therefore, how to analyze and evaluate the information superiority of data link And its influence on the overall information superiority of C ~ 4ISR system is an important research topic in data link system construction. Based on the analysis of workflow of C ~ 4ISR system, this paper gives the definition and evaluation model of evaluation index of communication subdomain information, and analyzes the data chain connectivity, transmission reliability and real - time information quality Then the mathematical description and evaluation model of data chain information superiority are given and the influence on the information superiority of C ~ 4ISR system is analyzed.
