摘要

针对传统通信信道路径损耗模型无法准确描述和表征感知信道的问题，开展面向6G通信感知一体化的亚太赫兹路径损耗测量与建模研究。基于雷达散射截面理论，引入室内材料回波特性的感知信道路径损耗，构建角度-距离联合的感知信道路径损耗模型。结合基于矢量网络分析仪的亚太赫兹感知信道实测数据，研究129.5~135 GHz频段内不同角度和距离下的感知信道衰落特性。实验结果表明，所构建的路径损耗模型能够准确刻画感知信道路径损耗随距离和角度遮挡因子的变化规律。

Abstract

To address the inadequacy of traditional path loss models in accurately describing and characterizing sensing channels

the research on sub-terahertz path loss measurement and modeling for 6G integrated sensing and communication was conducted. A sensing channel path loss model incorporating the echo characteristics of indoor materials was introduced based on radar cross-section theory and an angle-distance joint path loss model for sensing channels was constructed. Using a sub-terahertz channel measurement plat-form based on a vector network analyzer

the fading characteristics of sensing channels at different angles and distances were examined. The measurement results indicate that the angle-distance joint path loss model can accurately capture the variation patterns of sensing channel path loss with respect to distance and angular blockage factors.
