首先介绍了导引头截获目标过程的概率描述,分析了最优搜索范围与最优搜索形式。计算了目标落入导引头波束內的落入概率,据此选择一维搜索方式,并基于最优搜索形式设计了扫描搜索方案。该方案不但符合最优搜索的原则,而且可以获得更好的截获概率并降低对导引头的技术指标要求。研究结果可以对同类的自寻的导弹工程研制起借鉴作用。

In this paper, target acquisition probability of a seeker was introduced first, and then the optimal scanning area and scanning mode were analyzed. The probability of target falling into the seeker's beam was calculated, based on which an one-dimensional scanning mode was selected as the scanning mode. A seeker scanning program was designed for optimal scanning. So, a better acquiring probability can be obtained and this scanning concept not only meets the optimal scanning principle but also reduces the requirement for seeker's technical specifications. The study result can also provide reference for similar homing missile's engineering development.
