基于制导引信一体化的自适应起爆控制

Adaptive Detonation Control Based on Guidance Integrated Fuzing

引信与导引头一体化(GIF)设计是提高引战配合效率的有效途径。结合一般雷达导引头,首先介绍一种波控引信与硬件一体化引信进行设计,提出一体化引信起爆控制的逻辑算法流程;然后建立基于GIF信息条件下和基于引信自身信息条件下的两种弹目交会模型,并推导了最佳起爆角、起爆延时的数学表达式;最后分析计算几种弹目交会条件下,多普勒频率信息与自适应延时的对应关系。结果表明引信自适应延时起爆控制可以弥补GIF受干扰后不能提供起爆指令的不足,在整体设计中实现战斗部适时起爆。

The coordinated efficiency of fuze and warhead can be improved by integrated design of fuze and seeker. Firstly integrated with the generic radar seeker, the design of the GIF （Guidance Integrated Fuzing） combined with wave fuze is introduced together with the algorithm flow of the GIF burst control in this article. And the corresponding meeting model of the missile and the target is stated respectively based on the information of GIF and the fuze. The expression of optimum detonating angle and detonating time-lapse is also analyzed respectively in two models. Finally, the data of the Doppler information and the adaptive delay is calculated in some different corresponding meeting model. The result indicates that the burst control by adaptive delay can insure warhead burst adaptively in the design and offset the disturbed GIF, which can not provide burst instruction.
