红外成像导引头视场选择及搜索策略设计

视场的大小、形状及搜索策略是影响红外成像导引头截获概率的重要因素。在分析视场对导弹截获概率影响原理的基础上,定义了搜索场和截获场的概念,建立了不同视场形状和搜索策略的工作状态模型,并对常用的视场形状和搜索策略组合进行对比分析。仿真计算实例表明,截获场小于等于搜索场,采用不同的视场形状和搜索策略所获得截获场的大小不同,要根据设计需求优化选择。相关的研究方法和结论为红外成像导引头的视场选择和搜索策略设计提供了理论参考。

Field of view selection and search strategy design for infrared imaging seeker

The size, shape and search strategy of field of view are important factors which impact the acquisition probability of infrared imaging seeker. The theory that seeker's field of view impacting acquisition probability was analyzed, and on the basis, the concept of search field and acquisition field were defined. After that, several types of field of view working models were established and compared, which had different shapes and search strategies. The simulation and calculation cases indicate that the area of acquisition field is not more than search field, and different shapes and search strategies achieve different sizes acquisition fields, which should be optimally selected according to design requirements. The involved research methods and conclusions provide theoretical references to the field of view selection and search strategy design for infrared imaging seeker.
