摘　　要：地空导弹攻击过程可视化仿真包括数学模型的建立和可视化场景的实现,精确的数学模型是场景高度逼真的前提。分析了地空导弹在空气动力、发动机推力和重力作用下的受力情况,建立了在三点法引导时导弹攻击过程的运动方程组,并给出了目标在蛇形机动时导弹相应的三维弹道曲线。最后运用OpenGL图形库,研究了天空、地面以及导弹飞行尾焰和爆炸场景等特殊效果的生成方法,实现了导弹攻击过程的可视化仿真,较精确地再现了三点法引导时地空导弹的飞行过程。The visual simulation of ground-to-air missile＇s attack course comprises the establishment of mathematical model and the realization of visual scene. The mathematical model was required to be exact to meet the premise form the highly vivid scene. The strength accepted by the ground-to-air missile, under the aerodynamic force, booster thrust and gravity, was fully analyzed. Afterwards, the dynamical equation of the missile＇s attack process under three point trajectory was established, meanwhile, the corresponding three-dimensional trajectory of the missile was proposed when the target was in snaky mobility. Finally, the generative method of special effects, sky, missile flying trail fire, explosion scene, etc. was researched by applying OpenGL library. This realized the visual simulation of missile＇s attack process, and accurately represented the flight process of ground-to-air missile under three point trajectory.
