Aiming at different types of targets such as cruise missiles, stealth aircraft and aircraft cluster, the formation strategy, formation maintenance and reconfiguration, and battlefield situation information driving methods of UAV cluster are studied. By simulating the incoming target and designing the test scenario, the formation strategy of UAV cluster formation is preliminarily verified. The results show that the specific type of defense formation is used for different incoming targets, and then the interception strategies such as long distance, multi-layer, expansion, convergence, forward thrust and change of defense are used to block the incoming targets effectively, which can provide reference for the construction of air defense system.
