摘要

在车辆网络中，精确的车辆定位至关重要。本文提出了一种基于双功能雷达通信（DFRC）技术的联合路侧装置（RSU）和代理车辆合作定位框架。它利用无特征卡尔曼滤波（UKF）处理 DFRC 信号并获取车辆状态信息。为了提高代理车辆的角度预测精度，提出了一种基于最大似然算法的角度融合估计方案。此外，在 RSU 和代理车辆的联合协同定位中引入了一种加权方法，以提高车辆定位精度。实验结果表明，所提出的角度融合方案降低了角度估计误差，RSU 和代理车辆联合定位框架显著提高了车辆定位精度。

Joint RSU and agent vehicle cooperative localization using mmWave sensing

In vehicle networks, accurate vehicle localization is crucial. This paper proposes a joint roadside unit (RSU) and agent vehicles cooperative localization framework based on dual-function radar-communication (DFRC) technology. It utilizes unscented Kalman filtering (UKF) to process DFRC signals and obtain vehicle status information. To improve the angle prediction accuracy of the agent vehicle, an angle fusion estimation scheme based on the maximum likelihood algorithm is proposed. Furthermore, a weighted method is introduced within the joint RSU and agent vehicle cooperative localization to enhance vehicle localization accuracy. Experimental results demonstrate that the proposed angle fusion scheme reduces angle estimation error, and the joint RSU and agent vehicle localization framework significantly improves vehicle localization accuracy.
