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-Three-point method for three-dimensional kinematic trajectory simulation problem, create a simulation model of the first two models using numerical integration algorithm for three-point method kinematics equations, solving process is more complicated　second model using three-dimensional geometry of space-related knowledge, The three-point method for solving three-dimensional kinematic trajectory graphical method for solving a quadratic equation into the problem solving process so simple and intuitive Finally, the two models for simulation, and its application to air missile guidance and control system simulation study, the ideal trajectory were compared with the control trajectory results show that the two models are to solve the general case point method for solving the problem of three-dimensional kinematic trajectory, three-dimensional guidance law for the three-point method, and provides a ballistic characteristics method
