The thesis establishes a network simulation system for real - time confrontation of simulated air combat in order to evaluate the confrontation effectiveness and capability of air eombat, introduces the design approaeh, framework and function of the system and applies the least square fitting arithmetic in resolving the problems like the non - continuous track of simulated entity and the shaking of picture. Based on the Vega simulation software, it creates complex special effects of various kinds on battlefield and figures out the visualization of non - visual physical quantum. The system can make dynamic show of missile＇s attack to relevant target in different situations, including sorts of simulated information like special effects, sound effects, ete, with a fluent picture, a stable system performanee and a desirable interaetive capability. The visual simulation program, developed by means of Visual C ＋ ＋, resolves specific problems like visual drive and automatie viewpoint switching. The simulated result shows the simulated air combat process can be vividly represented in real time and an intuitionist evaluation of the combat effectiveness and capability is provided.
