基于网格的分布式雷达仿真系统关键技术研究

At present, the distributed radar simulation systems is almost developed based on HLA, and HLA provides complete solution to development and management of simulation application. However the distrbuted simulation system based on HLA is deficient in organizing and scheduling simulation resources, which leads to the simulation system is lacking in scalability and flexibility. The grid technology is aimed at managing many location and organization heterogeneous resources,and provides an distributed bottom supporting architecture of high performance computing and data processing. The grid offers an ideal solution to the upper problem in distributed simulation system development. This project will research on key technology of the distributed radar simulation system based on the grid.Through the in depth study the key issues of structuring radar simulation system architecture, dynamic scheduling strategy of the simulation system and the security policy in the grid environment, it is promising to breakthrogh the technical bottlenecks of the distributed radar simulation system and improve the simulation efficiency. The expected results of the project will enrich the theory of distributed simulation system, establish the architecture of the distributed radar simulation system based on the grid and improve the development of the simulaiton system, which has theoretical and practical significance for the distributed simulation system development.

目前，分布式雷达仿真系统大多是基于HLA进行开发。HLA对仿真应用的开发、管理提出了比较完善的解决方案。但基于HLA的分布式仿真系统缺乏对仿真资源的组织、调度使得系统缺乏弹性和灵活性。网格技术作为一种致力于管理众多地理上、组织上分布的异构资源并提供一种分布的高性能计算与数据处理的底层支持框架，为分布式仿真系统发展中遇到的上述局限提供了一种理想的解决方案。本项目拟研究基于网格的分布式雷达仿真系统的关键技术。通过深入研究雷达仿真系统框架的构建、仿真系统动态调度策略、网格环境安全等关键问题，突破分布式雷达仿真系统跨区域，安全高效仿真的技术瓶颈，提升仿真效率。项目的预期成果将丰富分布式仿真系统理论，建立基于网格的分布式仿真系统框架，提高仿真系统的性能，对我国分布式系统建设有重要的理论意义和应用价值。
