用于双功能雷达和通信的鲁棒通感一体化波束形成:方法和见解

Robust Integrated Sensing and Communication Beamforming for Dual-functional Radar and Communications: Method and Insights

Ahmad Bazzi, Marwa Chafii

摘要:

本文提出了一种新的稳健波束形成设计方法,用于通感一体化(ISAC)背景下的双功能雷达和通信(DFRC)基站(BS)。该架构旨在用于具有不完善的信道状态信息(CSI)的情况。我们建议的方法演示了几个权衡联合雷达通信部署。由于设计的DFRC性质,波束形成器可以同时指向预期目标,同时优化通信服务质量。我们揭示了一些见解,关于封闭形式的表达式,以及所提出的波束形成器的最优性。最后,仿真结果验证了所提出的ISAC波束形成器的有效性。

英文摘要:

This work presents a novel robust beamforming design dedicated for dual-functional radar and communication (DFRC) base stations (BSs) in the context of integrated sensing and communications (ISAC). The architecture is intended for circumstances with imperfect channel state information (CSI). Our suggested approach demonstrates several tradeoffs for joint radar-communication deployment. Due to the DFRC nature of the design, the beamformer can simultaneously point towards an intended target, while optimizing communication quality of service. We unveil several insights regarding closed form expressions, as well as optimality of the proposed beamformer. Lastly, simulation results demonstrate the effectiveness of the proposed ISAC beamformer.
