In response to the requirements of diversified joint operational patterns and agile utilization of airspace resources,a design of a joint airspace supervisory system is proposed.The capability features,the technical architecture model and the function classification are systematically introduced,and key technological aspects are also studied,such as real-time airspace data processing,dynamic airspace surveillance and airspace regulatory decision-making.With the focus on the critical technologies of the system and the measures,feasible solutions are proposed that effectively address the prominent problem of the lack of scientific and efficient technological means in current airspace supervision,providing a foundational and systematic model and technical guidance for the comprehensive,all-domain,and continuous airspace resource management mechanism and pointing out the developing direction of building the airspace supervisory system of the joint operations.
