地球旋转对弹道导弹射程的影响研究∗

摘要

研究了地球旋转对机动式弹道导弹发射阵地选择的影响问题。应用椭圆理论建立了弹道导弹自由段弹道模型，在相同的初始条件下，就是否考虑地球旋转对弹道导弹的射程分别作了计算，结果表明，地球旋转对导弹射程的影响随发射点纬度、射击方向和射程而变化，导弹射程越远，影响越大。%The influence of earth rotation on choice of firing position for motive ballistic missile was studied in this paper. The trajectory model of ballistic missile in free flight phase was established. Under the same initial conditions, calculations were accomplished with and without consideration of the influence of ballistic missile range, respectively. The conclusion is that the influence of earth rotation on the range of ballistic missile varies with the latitude of launch point, the launch orientation and the range of ballistic missile, and the influence is greater with increasing range.
