Research on HLA-based Satellite Cmmunication Link Distributed Simulation

该文首先对HLA进行了概述。其次介绍了卫星通信链路仿真系统的功能,该功能是由10个模型构成的基础模块和应用模块实现的;在此基础上提出了一种基于HLA的卫星通信链路分布式仿真系统的设计框架,构建了由11个联邦成员组成的卫星通信链路仿真联邦,并较为详细地阐述了仿真系统的联邦成员的设计和联邦成员间信息交互的设计,给出了联邦成员间信息传递关系的示意图,较好地解决了仿真系统各功能模型的同步、并行运行的问题;最后通过仿真得出了有关结论,为卫星通信链路、通信网络的设计与性能评估奠定了基础。

Firstly, in this paper the main content of HLA is summarized. Secondly, the functions of satellite communication link distributed simulation system are introduced, the functions are realized by basic module and applied module which consist of ten models ,then a design framework of HLA - based satellite communication link distributed simulation system is put forword,satellite communication link simulation federation which consists of eleven federates is built, and both the design of federates and the design of information interchange between federates are expatiated, the sketch map of information transfer between federates is given. The problem of how the function models of the simulation system can synchronously and paralleledly operate is well solved. Finally through simulation some relational conclusions are obtained, the foundation for both the design and the performance evaluation of satellite communication link and communication network is established.
