红外低轨星座突发任务多重策略调度方法

面向红外低轨星座的突发任务规划与资源调度问题，结合红外低轨星座的空间与时间分布特性，提出一种基于多重策略的红外低轨星座任务应急调度方法。所提方法结合红外低轨星座的设计特点，从星座全球分布的均匀性、结构的对称性及星座内卫星运动的周期性分析作为输入，提出一种以地理分区为长期值守分组策略与事件触发下基于相对运动分析的动态快速分组策略相结合的多重策略。在所提策略指导下完成任务分组，开展工作窗口调度。经仿真分析可得:所提策略可有效应对不同区域的目标触发，并实时完成分组及工作窗口规划调度，较好解决了任务突发情况下的系统响应，由于采用优先分组的策略，降低了全局优化的复杂度，具有创新性，且具备较好的应用价值。 

Burst tasks scheduling method for infrared LEO constellation based on multi-strategies

Aiming at problems of the burst task planning and resource scheduling of the infrared LEO constellation, a method based on multi-strategies is proposed considering the temporal and spatial distribution characteristics of infrared LEO constellation. And drawing on the design characteristics of infrared LEO constellation such as the uniformity of the global distribution, the symmetry of the structure and the periodic motion, this multi-strategies involve a long-term on-duty grouping strategy based on geographic divisions and the event triggering strategy based on relative motion analysis. Under the guidance of these strategies, this paper completes task grouping and carries out work window scheduling. Through simulation analysis, the multi-strategies reveal the effectivity, while dealing with target triggers in different areas and fulfilling of grouping and working window scheduling in real time, which insure the timeline of system response under task emergencies. Due to the priority grouping strategy, global complexity is reduced, and the method is proved to be innovative with practical application values.
