  • 适合研究抗干扰无人机系统或智能集群控制的工程师。

无人机群是自主系统的重要进展,通过机间通信实现协同任务,但依赖无线链路易受干扰影响。本文研究无人机群在干扰环境下维持通信与任务效率的能力。提出融合遗传算法(GA)、监督学习(SL)与强化学习(RL)的统一优化框架,将任务建模为分时分段的周期结构,支持动态路径规划、天线指向与群体编队,并逐步引入防碰撞规则。零点成形天线通过将波束零点对准干扰源提升抗扰能力。结果表明:GA生成稳定无碰撞轨迹但计算成本高;SL模型可复现GA配置但在动态或受限场景下泛化性差;基于近端策略优化(PPO)训练的RL展现强适应性与实时决策能力,通信保持稳定且计算需求更低。此外,自适应运动模型通过旋转机制实现任意方向移动,验证了系统的可扩展性。总体而言,配备零点成形天线并由智能算法引导的无人机群能有效缓解干扰,维持通信稳定性、编队一致性和避障安全。该框架为未来抗干扰集群通信系统研究提供统一、灵活且可复现的基础。

原文摘要 · Abstract (English)

Unmanned Aerial Vehicle (UAV) swarms represent a key advancement in autonomous systems, enabling coordinated missions through inter-UAV communication. However, their reliance on wireless links makes them vulnerable to jamming, which can disrupt coordination and mission success. This work investigates whether a UAV swarm can effectively overcome jamming while maintaining communication and mission efficiency. To address this, a unified optimization framework combining Genetic Algorithms (GA), Supervised Learning (SL), and Reinforcement Learning (RL) is proposed. The mission model, structured into epochs and timeslots, allows dynamic path planning, antenna orientation, and swarm formation while progressively enforcing collision rules. Null-steering antennas enhance resilience by directing antenna nulls toward interference sources. Results show that the GA achieved stable, collision-free trajectories but with high computational cost. SL models replicated GA-based configurations but struggled to generalize under dynamic or constrained settings. RL, trained via Proximal Policy Optimization (PPO), demonstrated adaptability and real-time decision-making with consistent communication and lower computational demand. Additionally, the Adaptive Movement Model generalized UAV motion to arbitrary directions through a rotation-based mechanism, validating the scalability of the proposed system. Overall, UAV swarms equipped with null-steering antennas and guided by intelligent optimization algorithms effectively mitigate jamming while maintaining communication stability, formation cohesion, and collision safety. The proposed framework establishes a unified, flexible, and reproducible basis for future research on resilient swarm communication systems.
