论文摘要
本文研究了双功能雷达通信（DFRC）系统的动态杂交波束形成（HBF），其中DFRC基站（BS）同时服务于多个单人体用户，并在存在多个夹具的情况下感知目标。特别是，我们在DFRC BS中应用带有动态子阵列的HBF架构和双相变。为了最大程度地提高雷达互信息，我们考虑共同设计DFRC系统的动态HBF，但受到通信质量（QOS），传输功率和模拟波束形式的限制。为了求解复杂的非凸优化，开发了一种基于多数化最小化方法的有效交替优化算法。仿真结果验证了所考虑的HBF体系结构的进步以及提出的设计方法的有效性。
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.
