始终处于大气层内飞行的TBM被动段弹道预测

对大气层内飞行的TBM弹道进行预测时,需要根据不同的应用要求,在求解精度允许范围内用近似方法对六自由度运动进行简化,获得简便实用的弹道预测方法。在假设获得TBM被动段弹道初始位置和速度参数的基础上,首先构建简便实用的处于大气层内飞行的TBM被动段抛物线弹道模型;然后将雷达测得的TBM被动段弹道初始位置和速度参数作为初始条件,对弹道方程采用精度较高的龙格-库塔法进行求解,相应得出被动段弹道上各点及落点的位置和速度参数,进一步确定出落点位置的地理位置经纬度。在某地空攻防对抗仿真项目中应用表明,弹道模型及其求解方法可应用于实战或较为逼真的仿真系统中。

Passive Trajectory Forcasting of TBM that is Always Flying in Aerosphere

While forcasting TBM passive trajectory in aerosphere according to deferent application requirement,6 freedom of motion need to be simplified by using approximate method in beg to untie precision limit,then convenient and practical ballistic forecast method can be obtained.On the assumption that original position and velocity parameter of TBM passive trajectory can be available,simple and practical passive section parabola ballistic model of TBM that is always flying in aerosphere was established,then original position and velocity parameter of TBM passive trajectory measured by early-warning radar was taken as initial condition,and then trajectory equation with Runge-Kutta method that is comparatively precise was solved,finally speed parameter and the location of each point and the landing point on passive section trajectory were obtained correspondingly,and the longitude and latitude of the landing point were calculated.The application in the simulation of offence-and-defense Antagonism of air-defense indicates that the trajectory model and its solution can be used in practical warfare and relatively vivid simulation system.
