基于联合通信和雷达传感的车辆波束跟踪
Vehicle Beam Tracking with Joint Communication and Radar Sensing
摘要
Abstract
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.关键词
