摘　　要：综合考虑天波超视距雷达任务实时变化特性和数据率限制影响,提出了一种基于动态多模板的天波雷达波位调度方法.首先,运用层次分析法对探测任务进行评估,通过任务重要性聚类确定波位调度的粗模板;然后,通过波位数据率的约束确定波位调度的精模板,明确搜索波位子集的划分方式.应用实例表明,该方法能够在复杂任务场景下动态调整优化天波雷达的时间资源,并能获得更高的探测效能.Considering the real-time change characteristics of sky-wave over-the-horizon radar(OTHR)mission and the influence of data rate limit,this paper proposes a method of sky-wave radar beam position scheduling based on dynamic multi-template.First,the analytic hierarchy process(AHP)is used to evaluate the detection mission,and the rough template of beam position scheduling is determined by task importance clustering.And then,the precise template of beam position scheduling is determined by the constraint of beam position data rate,so as to make clear the division way of searching beam position subset.Application examples show that this method can dynamically adjust and optimize the time resources of sky-wave radar in complex mission scenarios,and obtain higher detection efficiency.
