摘要:

毫米波集成感知与通信(ISAC)系统正在被研究用于下一代智能交通系统。在此,雷达和通信功能通过时分复用方式共享相同的频谱和硬件资源。雷达的目标是首先扫描角搜索空间,并在存在离散杂波散射体的情况下检测和定位移动用户/目标。随后,利用此信息将高定向波束定向到这些移动用户以提供通信服务。雷达参数如雷达占空比和相应波束宽度的选择对于实现高通信吞吐量至关重要。在本工作中,我们使用基于随机几何的数学框架来分析雷达操作指标作为雷达、目标和杂波参数函数,并随后利用这些结果研究ISAC系统的网络吞吐量。结果通过蒙特卡洛模拟进行验证。

英文摘要:

Millimeter wave integrated sensing and communication (ISAC) systems are being researched for next-generation intelligent transportation systems. Here, radar and communication functionalities share a common spectrum and hardware resources in a time-multiplexed manner. The objective of the radar is to first scan the angular search space and detect and localize mobile users/targets in the presence of discrete clutter scatterers. Subsequently, this information is used to direct highly directional beams toward these mobile users for communication service. The choice of radar parameters such as the radar duty cycle and the corresponding beamwidth are critical for realizing high communication throughput. In this work, we use the stochastic geometry-based mathematical framework to analyze the radar operating metrics as a function of diverse radar, target, and clutter parameters and subsequently use these results to study the network throughput of the ISAC system. The results are validated through Monte Carlo simulations.
