Research On Visual Simulation Technology In Ground Combat Information System Based On HLA

As one of the application direction of information technology and high-tech means, the ground combat information system is playing an important role in modern warfare. For such system, the way how to shorten the development cycle,accurately the reflect changes in the battlefield, are all problems that the ground combat information system design and development process have to face to. In order to resolve these issues distributed simulation technology provides a feasible way, but along with the developing of the simulation technology, the previous distributed simulation technology can not satisfy the requirements of the present simulation system that high visual and high fidelity in the process of simulation.Therefore, this paper puts the visual simulation technology into the ground combat simulation system, on the basis of research in real-time interactive technology between visual simulation software and other combat units, through the realistic, interactive and real-time features of visual simulation technology, the ground combat visual simulation system was designed and realized, and achieved the purposes that use the visual simulation system to display a realistic simulation process and render some parts of the battlefield.The research work in this paper mainly includes three parts:(1) Analysis the demands of the ground combat simulation system, puts the high level architecture HLA/RTI of distributed simulation technology and the visual simulation technology into the ground combat simulation system, establish the structure of the ground combat visual simulation system based on HLA, and design the function of each component unit;(2) In order to make visual simulation tool software (STK) display battle simulation process,aiming at the interactive operation problems between STK and each combat unit in the visual simulation system, STK-RTI link agency method was put forward, which is made as the link agent according to the HLA interface standard operates between STK and HLA/RTI, make STK adopt link agent through RTI to interact with other operational units;(3) According to the hypothetical scenarios, design the operational flow of the ground combat visual simulation system, research and design the problems that planning routing of vehicle, visibility of radar monitoring and real-time visual display in the simulation system.A simulation platform was build based on the above mentioned, use VC and STK mixing programming technology, accomplish the ground combat visual simulation system which is high real-time in the distributed simulation environment, realize the purpose that shows the realistic simulation process and render the effect of the battlefield.
