论文摘要
集成的传感和通信（ISAC）有资格通过雷达传感来检测和定位被动对象的移动无线电系统。高级ISAC网络依赖于网格的移动无线电访问节点（基础架构和/或用户设备，分别）建立一个分布式的多派MIMO雷达系统，在该系统中，每个目标都通过其Bistatic Backscattering来揭示自己。因此，对于ISAC绩效预测，靶标沿其运动轨迹的双基质反射率的表征最为重要。我们总结了在扩展的，潜在的时间变化雷达目标的任重建模和测量中的几个挑战。我们强调了分布式（因此多链接）ISAC网络引起的特定挑战，并与移动通信的传播建模相比，与最新的状态相比。
Integrated sensing and communication (ISAC) qualifies mobile radio systems for detecting and localizing of passive objects by means of radar sensing. Advanced ISAC networks rely on meshed mobile radio access nodes (infrastructure and/or user equipment, resp.) establishing a distributed, multistatic MIMO radar system in which each target reveals itself by its bistatic backscattering. Therefore, characterization of the bistatic reflectivity of targets along their trajectories of movement is of highest importance for ISAC performance prediction. We summarize several challenges in bistatic modeling and measurement of extended, potentially time-variant radar targets. We emphasize the specific challenges arising for distributed (hence multi-link) ISAC networks and compare to the state of the art in propagation modeling for mobile communication.
