机载激光链路快速捕获方法研究

摘要

为了研究机载激光链路的快速捕获方法,分析了初始引导方法和信标光捕获过程,以相对速度和分行扫描为基础,建立了最大捕获时间模型.模型考虑了重叠因子、链路距离、束散角、相对速度和目标线夹角等参数影响,并通过数字仿真,得出了快速建立机载激光链路的具体方法,对于机载ATP系统的设计和实际链路建立操作方法具有积极的指导意义.%In order to study the rapid acquisition of laser links between aircrafts, the preliminary guide and acquisition process of polar light are analyzed. The model of maximum acquisition time is derived based on the relative speed and scanning by rows. And the parameters such as overlap factor, link distance,beam divergence,angle between relative speed and target sight line etc are analyzed. Based on the numerical simulation, the method of rapid laser link establishing is suggested, which is of directing significance for the ATP system's design and practical application.
