摘　　要：无人机(UAVs)使用灵活、功能广泛,在军民领域均受到了广泛重视。但是,当前无人机的通信链路极易受到复杂环境干扰,从而严重影响使用效能。基于毫米波混合波束成形阵列提出了一种面向无人机动态通信的波束自适应追踪方法,利用对无人机运动轨迹的预测结果建立通信信道模型,并基于压缩感知算法开展混合波束成形设计,以实现对无人机目标的自适应实时跟踪。仿真表明,提出的波束跟踪方法可通过较小开销解决无人机动态飞行中面临的稳定通信问题,具有潜在应用价值。Unmanned aerial vehicles(UAVs)are flexible and versatile,and have received signifi-cant attention in both military and civilian domains.However,the current communication links of UAVs are highly susceptible to interference from the complex environment,which severely impacts their performance.A beam adaptive tracking method for dynamic UAV communication is proposed based on millimeter-wave hybrid beamforming arrays.By establishing a communication channel model used the predicted motion trajectory of the UAV and conducting hybrid beamforming design based on compressed sensing algorithms,the method aims to achieve adaptive real-time tracking of the UAV target.Simulations show that the proposed beam tracking method can address the issue of stable commu-nication during dynamic UAV flights with minimal overhead,demonstrating potential practical value.
