针对三点法三维运动学弹道仿真问题,建立了两种仿真模型。第一种模型采用数值积分算法求解三点法运动学方程组,求解过程较为复杂;第二种模型利用三维空间相关几何知识,将求解三点法三维运动学弹道的图解法转化为求解一元二次方程的问题,使求解过程简单直观。最后,对两种模型进行了仿真,并将其应用到地空导弹制导控制系统的仿真研究中,将理想弹道与控制弹道进行了对比。结果表明,两个模型均解决了一般情形下三点法三维运动学弹道求解的问题,为三点法三维制导律以及弹道特性研究提供了一种方法。
Aiming at the three-dimensional kinematic trajectory simulation problem, two simulation models are established. The first model uses the numerical integral algorithm to solve the three-point kinematics equations, the solution process is more complicated. The second model uses the three-dimensional space-related geometric knowledge to transform the solution method of the three-point kinematics trajectory into the one- Sub-equation problems, so that the solving process is simple and intuitive. Finally, the two models are simulated and applied to the ground-to-air missile guidance system simulation research, the ideal trajectory and control trajectory were compared. The results show that both models solve the three-dimensional kinematic trajectory problem of three-point method in general and provide a method for three-dimensional guidance law and ballistic characteristics research.
