Abstract
Since the UAV motion and attitude variations affect both communication and sensing performance,this paper presents a UAV channel estimation method that is augmented by the sensing information of the multi-modal sensor fusion.Firstly,an ISAC channel model is constructed by thoroughly considering the variations in UAV attitude and trajectory,and then a multi-modal sensor fusion approach tailored for ISAC is proposed.And then,the system state equation and observation equation for UAV-ISAC are derived,which incorporates the UAV motion patterns and quaternion attitude representation.Finally,the unscented Kalman filter(UKF)is utilized to integrate the outputs from multiple sensors,facilitating real-time acquisition of UAV trajectory and attitude information,and the channel is reconstructed to realize perceptual auxiliary communication.The experimental results conclusively show that the proposed UAV-ISAC method surpasses the traditional channel estimation techniques,which confirms its efficacy and potential.关键词
