Establishment of Mathematical Models of Target Movement in Simulation Tests

研究导弹飞行仿真试验中目标运动数学模型构建的一种方法.基于Bezier曲线算法,通过在飞行仿真软件窗口中编辑目标运动曲线,得到以vT,θT和ψT数据组描述的目标运动数学模型,并将这些数据组保存在MFC的集合类对象中.结果表明,利用该方法可以方便地实现飞行仿真试验中对目标运动特别是难于用解析式描述的目标随机运动数学模型的构建,使飞行仿真模拟简便易行.

A method for the establishment of target movement mathematical models is studied. By means of the data arrays VT, θT and ψT from a target movement curve edited in the window of the flight simulation software based on the Bezier curve algorithm, the target movement mathematical model is described. Then the data arrays are stored in an object of the MFC collection class. The simulation test results indicate that it is convenient to establish the model of the target movement, especially the random movement, which cannot be described by the mathematical equation. Thus the flight simulation can easily be implemented. Key words： simulation; mathematical model; Bezier curve
