Modeling And Simulation Of Artillery In The Simulative Training System Of "Tomahawk" Missile Interception

Simulative training is to achieve an important pillar of the military training modernization, and is one of the main objectives, but simulative training of our military is still "break up", "poor", "narrow", "less" and other issues, especially in the precision-guided target intercept. However,"Tomahawk"cruise missile is favored by USA, Britain and other military powers as a precise striking weapon. Artillery is the most effective interceptive weapon among numerous short-range anti-aircraft defense systems in less than 10km. Therefore, the study of"modeling and simulation of artillery in the simulative training system of'Tomahawk'missile interception"has great military and economic significance. Subject to the missile intercept as the prerequisite, the study which based on anti-aircraft artillery theory took application of virtual reality technology as its key, focused the modeling and simulation as target. The main researching content is as follows:(1) Summarized many basic theories such as characteristics and working processes of anti-aircraft fire control system, target motion trajectory model, firing table data processing, the choice of iterative algorithm and so on. The simulation workflow of fire control system in the Matlab platform was discussed. At the same time, Simulink was used to simulate the outer trajectory, the firing data of anti-aircraft and flying coordinates of artillery shell were obtained, which provided theoretical foundation for virtual visual simulation.(2) Discussed the modeling process by use of Creator. The complex models such as missile and anti-aircraft artillery were created by use of the combining method of Pro/E and Creator. In addition, in order to improve the quality and effect of modeling, many advanced modeling technologies such as Texture mapping, DOF, LOD and Billboard and so on were studied and realized. (3) The target of visual simulation and the process of implementation were designed. By use of Vega to read data from simulation of Matlab, the program was written by Vega API in the Visual C++ platform, realized the setting of firing data and the real-time update of flight state. In order to make the virtual scene more real and immersive, many kinds of weather conditions were set. Meanwhile, a lot of real-time processing technologies were studied and used, for example, the rendering of dynamic clouds and the application of collision, special effects, sound, etc.Finally, the paper carried out systematically summarizes for the research work. Aspects which needed to be improved were also discussed.
