Abstract: In order to cope with the emerging new air and space threat targets and the challenges brought by the new operational concept of ‘Mosaic War’, the collaborative detection and agile reconfiguration capability of the air and missile defense early warning network is required. The concept, connotation and basic form of synergy-netted detection cluster flexible architecture have been analyzed. The general design requirements of flexible architecture are presented, the flexible design method and process based on task-driven ‘agile reconfiguration’ are proposed. The capability requirements of flexible architecture to Synergy-netted Detection Cluster are also analyzed. The research results can provide technical guidance for the overall design of intelligent and flexible the air and missile defense early warning network in the future.
