基于摄动理论的爆高确定方法研究

分别讨论了两种通过飞行时间确定爆高的方法:解析计算修正法和时间偏导数法,这两种方法都是通过计算延迟时间来确定爆高,具有自主性强、可靠性高的特点。计算了两种方法在不同干扰条件下的结果,分析了造成计算偏差的原因。计算结果表明,两种方法的计算误差都非常小,均可应用于弹道导弹爆高确定。

On the Method of Determinating Explosion Height Based on Perturbation Theory

Determinating an explosion height is an important factor for realizing the power of ballistic missiles.Two kinds of methods of determinating the explosion height through flight time are discussed in this paper,and one is the analytic computation and compensation method,while the other is the time partial derivative method.Both methods determine the explosion height through computing the delay time,and have high autonomy and reliability.The explosion heights in different disturbed conditions are computed by these two methods,and the reasons for the computation deviation are analyzed correspondingly.The computational results show that the computation deviation of these two methods is very small,which means that both methods can be used to determine the explosion height of a ballistic missile.
