摘要
近年来电子侦察卫星规模化发展,并且具备星上数据处理能力,专用卫星接收终端可以同时接收数颗卫星下传的星上处理信息,有效提升航天电子侦察时效性。但其接收能力有限,会引起星上处理下传数据冲突。研究卫星终端星上处理数据接收资源优化问题,给出多星星上处理下传任务冲突有向图模型和资源决策优化方法。仿真分析表明,在目标较多的情况下,该方法既均衡了各卫星载荷星上处理数据的贡献,又突出各载荷优势,最大化侦察效益。
In recent years,electronic reconnaissance satellites owning the ability of real-time data processing develop on a large scale.The existing dedicated satellite receiving terminals can receive muti-satellite processing information at the same time,which effectively improve the timelines of aerospace electronic reconnaissance.However,their receiving capacity is limited,which will lead to data collision.Therefore,it is necessary to research the optimization of data resource for satellite receiving terminals.The directed graph model for data collision of mutisatellite processing information and method of resource optimization are proposed.Simulation results show that the method is available for targets increasing more and more,which not only balances the contribution of the reconnaissance data of each satellite,but also highlights the advantages of each payload to maximize the efficiency of electronic reconnaissance.
