Abstract: In order to seize decision and action superiority, intelligent electromagnetic spectrum operation needs prepared strategy to design and control operations. Strategies such as tridimensional distributing sensing, cluster attacking, differentia layered defense, dynamic spectrum sharing based on frequency usage rules, operation resource scheduler based on effects are designed. Electromagnetic spectrum operation strategy architecture is constructed by electromagnetic spectrum combat mechanism, combat conflict resolution strategy, operational rules, operational policy, regulation and principle, spectrum management strategy is derived as an example. Dynamic and low coupling ontology model for electromagnetic spectrum operation strategy is designed, and every strategy is described using eight tuples. The designed electromagnetic spectrum operation strategy architecture based on-line processing includes data overhead layer, metadata layer, autonomous data layer, application area, data storage area and so on.
