Abstract

Multi-agent electronic jammers and information sharing mechanism was used to break through the limited information perception ability of the original single sensor in order to realize the effective jamming of radiation source in complex electromagnetic environment. Then real-time dynamic situation information sharing was realized, and the intelligent decision cognition ability of electronic jammer was enhanced. The rapid convergence of the microsecond-level about the jamming parameters was achieved by the multi-agent independent electronic jamming system based on information sharing, and the information error probability in a single-jammer conditions was reduced. The experimental results show that the jamming parameter update strategy based on the method is adjusted in real time with the dynamic change of situational environment. A more autonomous and intelligent cognitive electronic jamming system is realized.

Key words： information sharing multi-agent electronic jammer Q-Learning situational awareness

基于信息共享的多智能体自主电子干扰系统

为了实现电子干扰机在复杂电磁环境中对辐射源的有效干扰，利用多智能体电子干扰机与信息共享机制，突破原有单传感器的有限信息感知能力，实现实时动态态势信息共享，增强电子干扰机的智能决策认知能力. 基于信息共享的多智能体自主电子干扰系统实现了μs级的干扰参数快速收敛，减小了单传感器的信息误差概率. 通过仿真实验表明，基于该方法的干扰参数更新策略随着态势环境的动态变化而实时自主调整，实现了更加自主与智能的认知电子干扰系统.
