摘要:

本文研究了dual-function radar-communication (DFRC)系统的动态混合波束成形(HBF),其中DFRC基站(BS)在存在多个杂波的情况下同时服务多个单天线用户并感知目标。特别地,我们在DFRC BS中应用了具有动态子阵列和双移相器的HBF架构。旨在最大化雷达互信息,我们考虑联合设计DFRC系统的动态HBF,受限于通信服务质量(QoS)、发射功率和模拟波束成形器的约束。为了解决复杂的非凸优化问题,开发了一种基于majorization-minimization方法的高效交替优化算法。仿真结果验证了所考虑的HBF架构的先进性和所提出设计方法的有效性。

英文摘要:

This paper investigates dynamic hybrid beamforming (HBF) for a dual-function radar-communication (DFRC) system, where the DFRC base station (BS) simultaneously serves multiple single-antenna users and senses a target in the presence of multiple clutters. Particularly, we apply a HBF architecture with dynamic subarrays and double phase shifters in the DFRC BS. Aiming at maximizing the radar mutual information, we consider jointly designing the dynamic HBF of the DFRC system, subject to the constraints of communication quality of service (QoS), transmit power, and analog beamformer. To solve the complicated non-convex optimization, an efficient alternating optimization algorithm based on the majorization-minimization methods is developed. Simulation results verify the advancement of the considered HBF architecture and the effectiveness of the proposed design method.
