标题： Correlation and Temporal Consistency Analysis of Mono-static and Bi-static ISAC Channels

摘要： 集成感知与通信（ISAC）对于未来无线网络如6G中的高效频谱和硬件利用至关重要。 然而，现有的信道模型缺乏对ISAC特定动态的全面表征，特别是单基地（收发共置）和双基地（分离的收发）感知配置之间的关系。 在动态城市微小区（UMi）环境中使用79-GHz FMCW信道探测器进行的实测有助于填补这一空白。 展示了两个关键发现：（1）由于传播几何结构的不同，单基地和双基地信道表现出一致的低瞬时相关性；（2）尽管瞬时相关性较低，但两个信道在环境运动学下具有统一的时间一致性，可以预测地演变。 这些见解在七个包含移动目标/收发器的真实场景中得到验证，为鲁棒的ISAC系统设计和未来标准化提供了依据。 显示英文摘要

摘要： Integrated Sensing and Communication (ISAC) is critical for efficient spectrum and hardware utilization in future wireless networks like 6G. However, existing channel models lack comprehensive characterization of ISAC-specific dynamics, particularly the relationship between mono-static (co-located Tx/Rx) and bi-static (separated Tx/Rx) sensing configurations. Empirical measurements in dynamic urban microcell (UMi) environments using a 79-GHz FMCW channel sounder help bridge this gap. Two key findings are demonstrated: (1) mono-static and bi-static channels exhibit consistently low instantaneous correlation due to divergent propagation geometries; (2) despite low instantaneous correlation, both channels share unified temporal consistency, evolving predictably under environmental kinematics. These insights, validated across seven real-world scenarios with moving targets/transceivers, inform robust ISAC system design and future standardization.
