Research on control strategy of EWA air defense alert within synthesis combat area

The control strategy of early warning aircraft (EWA) assigned by carrier formation aimming at multi-target air defense alert within synthesis combat area is investigated. Firstly, the patrol program generation process of EWA is analysized. Then taking the process as the mainline, enemy combat capability and combat profile as well as the warning area of ship formation and EWA are studied. On this basis, taking the airspace grid as the unit, the corresponding evaluation method of warning effect and threaten degree are studied. Secondly, by analyzing the actual demand, three types of patrol strategy planning model available for warning tasking shifting, which is composed of "sorties specified type", "cost unconsidered and sorties unspecified type" and "cost considered and sorties unspecified type", and their corresponding parallel genetic algorithm of multi-master-single-slave structure are presented. Experiments show that the established model can realize the corresponding function of patrol strategy planning, and the proposed algorithm can solve the corresponding model efficiently. The validity of the model and algorithm is demonstrated.
