| 摘 要： | 空中目标运动轨迹的数学建模是防空兵虚拟战场中作战仿真的关键,为有效和逼真模拟空中目标运动轨迹的变化情况,在分析了目前空中目标三种典型运动轨迹特点的基础上,提出了采用B样条函数的方法来描述目标三维运动轨迹,并根据目标飞行过程中过载、最大飞行速度等条件的限制,结合地形坡度的变化,对拟合结果进行了重新规划。通过仿真实验,证明该方法能够较好地拟合空中目标的飞行轨迹,实时解算的目标参数符合其飞行规律,为推演防空作战过程提供了必要的条件支撑。

| Abstract: | Moving model of aircraft is the key to martial simulation of air defense force.In order to simulate moving-track of aircraft effectively and realistically,in this paper,an algorithm is raised.Firstly,analyze three basic moving characters of aircraft,and then,design the method to simulate the moving track of aircraft based on B-spline function.Lastly,recount track based on changes of terrain-slope's,considering some factors such as max-speed and overload of aircraft.The experiment shows that the algorithm ca... |
