为满足导弹作战虚拟仿真系统的需求,采用分布交互仿真高层体系结构(HLA)和虚拟现实技术,结合导弹作战系统特点,设计基于HLA和Vega Prime的某型导弹武器仿真系统,描述其系统功能特点.在介绍HLA/RTI并分析导弹作战系统工作原理的基础上,提出导弹作战虚拟仿真系统的解决方案,介绍系统的三维虚拟场景建模、联邦成员模型、仿真对象模型以及成员接口的设计与实现,最后实现导弹武器系统的整个仿真过程.研究结果表明;HLA是建模和仿真的通用技术,虚拟仿真技术是现代仿真技术的重要发展方向,解决了虚拟现实问题并使仿真的可视化程度大大提高;该系统具有良好的可操作性、可扩展性和实时性.%In order to meet the requirements of missile combat virtual simulation system, combined with the feature of missile combat system, the high level architecture (HLA) of distributed and interactive simulation and virtual reality technology were applied to the system. Based on the technology of HLA and Vega Prime, the function, peculiarity and architecture of the system were proposed. HLA/RTI was briefly introduced and the principle of the combat simulation system was analyzed, a technical scheme of the combat system based on HLA and Vega Prime was described, and the combat system was implemented. On this basis, three dimensions object modelings, i.e., the design of federation object model, simulation object simulation model and the interface of federation member, were introduced. The results show that HLA is a common simulation architecture, and Virtual Reality is an important developing direction of simulation technology, and the problem of virtual reality is solved and visualization effect is improved greatly. The simulation system meets users' needs perfectly, and each component can be customized due to individual needs.
