针对弹道导弹末段突防问题,应用层次性能评估体系,对弹道导弹末段典型突防制导律进行对比分析。并通过对弹道导弹制导精度、弹道导弹最大过载、弹道飞行时间和反导导弹脱靶量以及它们的均值、均方差的重要性和需求性分析,合理设置评估体系的指标及其权值,应用随机仿真分析方法,对比仿真经典比例导引、修正比例导引和变结构比例导引三种突防制导律的性能。仿真结果证明,层次评估理论可以用于弹道导弹末段突防制导律的评估及优选。

There is a problem at the end of the trajectory of ballistic missile which is the optimal guidance law of breaking through the defense system. For that problem,we could analyze different guidance laws by using the multiple-stage analyzing theory. As we analyze the means and variances of the precision,the maximum of the overload,the flight time and the precision of the anti-missile,we can assess the performance and importance of the guidance laws. And then,we set up reasonable parameters of the analyzing theory. And after random simulation,we will get the score of different guidance laws by using it. The result of simulation proves that the AHP can be used in choosing and optimizing guidance law at the end trajectory of ballistic missile.
