现代空战多为机群对机群的空战。针对无人机群空战中协同攻防机动决策的问题,首先提出了针对单机对单机的在不确定环境下基于多级影响图的空战决策建模。在此基础上对无人机群进行分组,并根据无人机的空战能力划分角色,在空战初始确定小组内的长机与僚机。通过引入协同因子,对空战机动决策中的当前局势概率重新进行加权修正,很好地解决了单元内各成员协同配合的问题,从而将单纯的一对一空战引申为多机对多机协同空战。仿真结果表明所建立的决策模型能够有效地解决无人机群协同空战的机动决策问题。
The problem of cooperative attack-defense maneuver decision-making for UCAV fleet was studied.First,an air combat decision-making model for single UCAV against single UCAV in uncertain condition was built up based on multistage influence diagram.Based on this,the UCAVs were divided into groups,and each UCAV was assigned a role according to its operational capability.The leader and wing plane of each UCAV group were determined.Then the cooperative factor was imported to recalculate the probability of current situation more effectively,and the cooperation of each member in one unit was implemented.Consequently,the one to one air combat could be extended to group to group air combat.Simulation results showed that the decision-making model built in this paper can solve the maneuver decisions of the cooperative air combat for UCAVs effectively.
