Abstract: When faced with massive data on radio signal detection and surveillance,the simple storage and queries fail to meet the application requirements.In order to satisfy the requirements of higher level decision making in radio monitoring system and intelligent monitoring services,a radio monitoring data warehouse was designed based on the preprocessing of the data collected from existing radio monitoring system.First,ETL (Extract/Transform/Load) rules were defined to collect data from application systems and information platforms.Second,an unknown signal data cube was built after the design of dimensions,measures,and levels.Finally,the implementation of analysis,prediction and decision-making functions based on multidimensional data models was done.It helps to enhance the business functions relatedwith unknown signals.
