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.
