摘要: 利用椭圆方程导出弹道导弹自由飞行段的射程公式,并根据该关系式推出当自由飞行段的起始速度给定后,射程最远时对应的弹道倾角和最大射程,给出几个估计弹道参数的例子.

Abstract: The range formula of free flight section of ballistic missile is derived by using the elliptic equation. When the initial velocity of the free flight section is given,the maximum range and corresponding trajectory inclination angle are deduced by the range formula. And several examples of estimating ballistic parameters are given.

Key words: ballistic missile, elliptic orbit, range, trajectory inclination angle
