Research On Air Defense Missile Fighting Simulation System Base On HLA And VR

With the development of computer simulation technology, simulation technology has been applied more and more widely to the industry and the research of defense, however, as the complexity of problems increased, single simulation system hasn't satisfied requirement, and distributed simulation basing on multi-system has become necessary of simulation. Large-scale simulation generates a great number of data, scientists and engineers should take much time and energy to analyze the data which are always boring numerals and symbols. The development of computer science and computer graphic brings the virtual reality technology, which could present real environment and express the simulation process objectively by special equipment, providing a visual and vivid simulation analysis means. Therefore, the virtual reality technology extricates scientists and engineers from the boring data thoroughly.The high level architecture of distributed and interactive simulation and virtual reality technology has combined to the study of air defense missile weapon fighting simulation. A distributed and interactive air defense missile weapon fighting simulation system is developed, and some important aspects in the system are studied.Firstly, the evolution of distributed and interactive simulation and virtual reality technology is introduced, the background of air defense missile weapon fighting simulation system is discussed in detail, and the structure of simulation system is designed as well.Secondly, how to implement the simulation on high level architecture is researched, the federation conceptual model and the federation object model are set up, and the federate is constructed.Thirdly, the object of system is analyzed, the method and process of three-dimensional geometric object model is studied, and the three-dimensional geometric object model and the motion model are set up.At last, the virtual reality interface of the federate is designed, the virtual scene integrating and driving technique is researched, and an application definition file is created.The air defense missile fighting simulation system made in this paper simulates the...
