摘　　要：针对巨星座通联面临频轨资源稀缺、节点高动态、传输距离跨尺度等挑战,传统无线空口技术较难满足高安全、高可靠、低时延通联的通信需求,研究巨星座跨域多尺度安全传输与接入技术,遵循“感知环境-利用环境-适应环境”的研究思路,提出了电磁环境认知驱动传输与接入机制,采用电磁地图知识构建立体电磁态势图,深度挖掘不同维域可用通联资源,在此基础上通过统计预先规划与实时动态操控双驱动,利用自主决策接入方式,实现高动态、多尺度、复杂通联环境下的时/空/频/能等碎片化通信资源高效利用,确保信息高安全传输,进而保障巨星座网络的安全可靠连接,推动天基信息系统支援能力建设。In response to the challenges faced by mega-constellation communication,such as scarce frequency and orbital resources,highly dynamic nodes,and cross-scale transmission distances,traditional wireless air interface technologies struggle to meet the communication requirements for high security,high reliability,and low latency.This study focuses on cross-domain multi-scale secure transmission and access technologies for mega-constellations,following a research approach of“sensing the environment-utilizing the environment-adapting to the environment.”An electromagnetic environment cognition-driven transmission and access mechanism is proposed,leveraging electromagnetic map knowledge to construct a electromagnetic situation map,deeply explores the available communication resources in different dimensions.Building on this foundation,a dual-driven strategy combining statistical pre-planning and real-time dynamic control is implemented.Through autonomous decision-making access methods,the efficient utilization of fragmented communication resources such as time,space,frequency,and energy in highly dynamic,multi-scale,and complex communication environments is achieved.This ensures high-security information transmission,thereby guaranteeing secure and reliable connectivity for mega-constellation networks and advancing the development of space-based information system support capabilities.
