Unmanned aerial vehicle (UAV) cluster operation is an important operation mode in the future.The research on the generation mode of UAV cluster intelligence and the way to realize it is the basic support for the determination of UAV cluster operational organization and operational design.Firstly,the centralized,bionic and function distributed generation model of UAV cluster intelligence is proposed,and the corresponding ways of realization are discussed in general.Secondly,the way to realize intelligent effect of task adjustment and route replanning in war is proposed, based on parallel system architecture.Finally,the way of route search,attack and optimization based on emergence of bionic behavior intelligence is proposed.
