In order to solve the problem of jamming power allocation in battlefield cooperative communication countermeasures,this paper designs a distributed cooperative jamming power allocation method based on multi-agent deep reinforcement learning.Specifically,modeling the communication jamming power allocation as a fully cooperative multi-agent task,then the framework of centralized training and distributed decision-making is adopted to alleviate the characteristic of non-stationary environment and high dimensions in multi-agent system,reducing the communication overhead between agents as well,and introducing the maximum policy entropy criterion to control the exploration efficiency of each agent.Regarding maximizing the cumulative jamming reward and maximizing the entropy of the jamming policy as the optimization goal,then accelerates the learning of cooperative strategies.Simulation results indicate the proposed distributed method can effectively solve the high-dimensional cooperative jamming power allocation problem.Compared with the existing centralized allocation method,it has faster learning speed and less volatility,and the jamming efficiency is 16.8%higher than that of the centralized method under the same conditions.
