【摘要】 战术数据链的基本作用是保证战场上各个作战单元之间迅速交换情报信息，共享各作战单元掌握的所有情报，实时监视战场态势，提高相互协调能力和整体作战效能。战术数据链在现代战争中发挥着极其重要的作用，数据链的建设是信息化战争发展的重要标志之一，数据链的应用水平在很大意义上决定着信息化战争的水平和能力。战术数据链是数据通信技术在军事方面的典型应用，主要采用通信网络技术和应用协议，实现机载、陆基和舰载战术数据系统之间的新型数据交换及战术系统的各项功能，因此组网协议的研究是数据链系统工作的核心。本文首先介绍课题的研究背景、国内外研究现状、研究内容及技术路线；第二章系统地总结战术数据链的分类、作用、特点及基本结构；第三章介绍了本文所研究的战术数据链的协议，战术数据链系统协议采用信道组网协议，并详细描述了协议中网络体系、网络运行模式、数据处理流程、轮询协议运行、组网实现以及链路操作过程；第四章是仿真建模，这也是课题的重点，该章根据第三章的协议设计在Qualnet仿真软件下进行战术数据链MAC(Medium Access Control)层建模，同时在单链模型基础上建立了战术数据链多链模型；第五章是仿真实验及结果分析，该部分首先在单网模型下做了大量实验对战术数据链系统MAC层系统响应时间、端到端时延、网络循环周期等实时性指标进行分析，然后研究了战术数据链系统多链性能，给出了战术数据链系统多链情况下网络节点跨网传递消息的时延实验，结合应用，通过对实验结果分析发现了战术数据链应用层消息端到端时延的变化主要取决于MAC层端到端时延的变化。总之，本文根据要求对战术数据链的MAC层进行仿真建模，同时根据需要，建立了战术数据链多链模型，通过大量的仿真实验，分析了单网和多网情况下影响战术数据链实时性能的指标，对实际应用提供一定的参考。更多还原

【Abstract】 The basic function of Tactical Data Information Link(TDIL) is to guarantee that intelligence information can be exchanged in real time and shared among combat units, battlefield situation is under continuous real-time surveillance, so the ability of cooperation each other and the effect of joint operations are effectively improved. The multi-link simulation of TDILdirectly influences the evaluation of the TDIL’s application performance.TDIL is representative application of data communications in military affairs. TDIL adoptes communication network technology to achieve new type data exchange among air Platform、army and navy. So the kernel of data link system is to research network protocol.Firstly, study background & actuality、study content and technical route of the thesis were introduced in chapter 1. Based on TDIL, the thesis summarized sort、function、characteristic and basic architecture in chapter2. On the basic of protocol of TADIL,in the thesis, polling protocol was adopted. Network configuration、data processing、protocol operation、network implementation and link operating procedure were particularly introduced in chapter3. In chapter 4, the thesis developed a MAC module of TDIL based on the QualNet simulation platform.In chapter 5 the thesis maked experiments with some scenes, some simulation results and analyses were given at the end. The result indicated that changed delay of TADIL message in application layer of TDAIL application layer accord with changed delay of TADIL message in MAC layer.In conclusion, MAC model of TDIL was designed in the thesis,as well as modeling multilink configuration. Through many experiments,the thesis analysed system performance.The results indicated that the system can meet the requirements of tactical and technical index in some condition, and had reference and guide value in engineering application.更多还原
