Abstract: Intelligent air warfare characterized by intelligence, distribution and cloud cooperation is the trend of future warfare, and the operation window of modern war is extremely compressed, poses a great challenge to the traditional airborne early warning and detection system. Although the concept of the future airborne intelligent early warning and detection system has not been clearly proposed, the concepts of "combat cloud", "unmanned swarm", "Mosaic warfare" and "penetrating counter air" have been put forward intensively, which have reflected the prototype of the future airborne intelligent early warning and detection system. In this paper, an airborne intelligent early warning and detection system based on intelligent processing control unit is proposed. The system can realize the perception of individual intelligence, swarm intelligence and sensor interconnection in the system, so as to achieve the purpose of single platform intelligence detection and multi-platform intelligence collaboration. The conceptual of airborne intelligent early warning and detection system is introduced, the application efficiency of the connotation system is evaluated, and the key technologies related to the system are analyzed in this paper.
