摘　　要：波束跟踪是面向高移动性车载毫米波通信的关键问题之一。通过构建车辆状态演化模型模拟车辆的水平和垂直运动状态变化特性,利用毫米波通信的大带宽和均匀平面阵列天线,设计基于雷达通信双功能信号的状态参数估计方案。基于雷达回波感知信号和车辆反馈信息构建的测量模型,使用扩展卡尔曼滤波对车辆的状态参数进行预测。结果表明,该方案能够更准确地跟踪车辆的移动,预测波束方向,有利于通信。Beam tracking is one of critical issues for millimeter-wave communication in high-mobility vehicular scenarios.By constructing a vehicle state evolution model to simulate the horizontal and vertical motion state change characteristics of the vehicle,the state parameter estimation scheme based on dual-functional radar and communication is designed by using the large bandwidth of millimetre wave communication and the uniform planar array antenna.In addition to radar echo perception,the feedback signal emitted by the vehicle is also added in the measurement model,and the extended Kalman filter is used to predict the state parameters of the vehicle.The results show that the scheme can track the movement of the vehicle more accurately,predict the beam forming direction,and thus facilitate communications.
