Abstract: Capacity is one of the important index to evaluate tactical data link system performance.An effective and accurate analysis method is needed to understand the influencing factors of tactical data link system capacity.By taking Link 16 data link system as the research object,the paper mainly analyzes the restrictive relationship between delay and capacity.After defining the capacity of Link 16 data link system,the model of Link 16 is introduced,and the sufficient and necessary condition for estimating the capacity of which with delay constrain is given.At last,the capacity of Link 16 system as an application example is provided.

Key words: Link 16 data link, Time Division Multiple Access(TDMA), delay, capacity

摘要: 容量是评价战术数据链系统性能的重要指标。有效、精确的容量分析方法有助于深入认识影响战术数据链系统容量的诸多因素及其相互关系。以Link 16数据链系统为研究对象,分析了时延与容量之间的约束关系。首先给出了Link 16数据链系统容量的定义,然后通过建模分析研究了在时延约束下Link 16数据链系统容量问题,给出了计算其容量的充要条件。最后通过实例分析验证了分析的有效性。
