求解定向战斗部最佳起爆延迟时间和起爆方位的一种方法

起爆控制技术是装备定向战斗部的空空导弹的主要技术之一。综合利用制导和引信信息确定引信最佳起爆延迟时间和起爆方位是导弹技术发展的方向。该文在弹体坐标系下建立了任意空间交会条件下定向战斗部最佳起爆延迟时间和起爆方位的数学模型，通过仿真计算对弹目交会特性进行分析。研究表明，起爆方位角的变化与弹目相对速度无关；在最佳起爆延迟时间段，目标的方位可能发生象限变化。因此定向引战系统必须根据起爆方位角变化调整起爆方位才能有效击毁目标。

A solving method of optimal initiating delay time and initiating direction for aimed warhead

The technology of the initiation control has been one of the chief technologies of the air to air missile equipped with the aimed warhead.To determine the optimal initiating delay time and initiating direction of the aimed warhead by using synthetically the guidance information and the fuze information is the developing direction of the missile technology.The calculation models of the optimal initiating delay time and initiating direction of the aimed warhead at an arbitrary encounter conditions in missile coordinate are set up in this paper.The encounter feature of missile and target is analyzed by using simulation calculations.The study shows that the initiating direction has nothing to do with the relative velocity of the missile and the target;the direction of the target may change a quadrant in the period of the optimal initiating delay time.In order to destroy the target,the aimed fuze and warhead system must adjust the initiating direction according to the change of the initiating direction.
