摘要
本文研究了导弹的六自由度（６ＤＯＦ）空间运动制导系统的基本特性、建立了导弹随机飞行模块化数字仿真结构。在随机干扰作用下，应用协方差分析描述函数技术（ＣＡＤＥＴ），分析弹着点的散布，获得了较满意的结果。文中主要讲述了方波控制的导弹的有关问题，但所给方法对其它类型的导弹也是同样适用的。
A study of 6 DOF (six degree of freedom) motion'of guided missile has been carried out by using the CADET (Covariance Analysis Describing Function Technique)method. Secondly, a digital simulation struture that has good expansibility and transplantation has been introducsd. Some important factors have been analyzed which affect the miss distance of missile. It is shown by the working example that the results obtained are mostly satisfactory.Although the 'bang-bang'control law is mainly discussed, it is pointed out that the method can be used for the other conditions.
