建立导弹的运动学与动力学模型，作用于导弹上的力、力矩及加速度、速度、位置、姿态等运动参数之间关系都由该模型定义,模拟导弹反导轨迹。(The kinematic and dynamic model of the missile is established, and the relation between the force, torque and acceleration, velocity, position and attitude on the missile is defined by the model, and the missile's anti missile trajectory is simulated.)
