Method of Guidance Handover in Beyond-visual-range Coordinated Air-combat for Multi-UCAVs

UCAV has superior mobility and stealth performance while the stability of communication system and intelligence level are poor at present. According to these features, a beyond-visual-range coordinated air-combat mode for multi-UCAVs was proposed. To investigate the handover of guidance power from intermediate-range air-to-air missiles to other friendly UCAVs, a method of guidance handover was proposed. The process of guidance handover was analyzed in principle. Then the situational superiority models of UCAVs to the missile whose guidance power needed to be turned over and the target of missile were established. Based on these models, the comprehensive guidance superiority model of UCAVs was constructed. The strategy of guidance handover was designed according to this model, and solved by particle-swarm optimization algorithm. The reasonable handover of guidance power among multi-UCAVs was realized, and the survivability and autonomous decision-making capacity of UCAV were improved to some extent. The simulation result verifies the feasibility and validity of the method.
