该模块通过应用目标质心的动力学方程式，根据目标质心作用力 、 、 ，求出目标的速度 、弹道倾角 、弹道偏角 ；再通过目标质心的运动学方程式，即可计算出每一时刻目标位置（ ， ， ）(By applying the kinetic equation of the centroid of the target, the velocity of the target, the inclination angle and the ballistic angle of the target are calculated according to the force of the centroid of the target, and then the position of the target can be calculated by the kinematic equation of the centroid of the target.)
