【摘要】 频谱是一种承载无线电通信的自然资源,无线电管理部门需对其管辖范围内的无线电通信进行监测和管理,保障频谱资源被高效有序地使用.可视化与可视分析作为一种数据分析、信息挖掘和辅助决策的重要技术,广泛应用于分析各类仿真和监测获得的电磁大数据,以提升管理人员在无线电信号识别、无线电行为理解、通信干扰检测与处置、电磁环境态势感知等方面的能力.通过整理2000—2020年的相关文献,首先总结无线电监管发展历程和数据分析需求;然后从科学可视化、信息可视化和可视分析3个方面系统地梳理已有研究和应用场景;最后展望了该领域未来的研究方向.更多还原

【Abstract】 Electromagnetic spectrum is a natural resource to support radio communications. Radio administration bureaus need to monitor and manage radio communications within their jurisdictions to ensure the efficient and orderly use of spectrum resources. Visualization, as an important technology for data analysis, information mining, and decision making, has been widely applied in the analysis of big radio data to improve the ability of radio supervisors in signal recognition, radio behavior understanding, interference detection and treatment, and electromagnetic situation awareness. In this paper, we present a literature review of visualization for radio monitoring and management. We first summarize the development of technology in radio monitoring and management and the analysis requirements of radio big data. We then introduce representative visualization approaches for radio monitoring and management from three main perspectives, namely scientific visualization, information visualization, and visual analytics. Finally, we outline some guidelines and directions for future research.更多还原
