双功能雷达通信（DFRC）设计是解决具有挑战性的频谱拥塞问题的一种有前途的方法。本文考虑了 DFRC 系统的联合天线选择和数字波束成形设计，该系统服务于多个多播通信组，同时执行感知。双功能发射设计被认为是通过联合选择天线和设计波束形成器来最大化多个目标方向上的最小目标照明功率，该波束形成器受到通信用户的信号与干扰加噪声比（SINR）的下限和每个杂波散射体处的杂波功率的上限的影响。由此产生的优化公式是一个混合整数规划问题，可以使用惩罚顺序凸松弛方案和半定松弛 (SDR) 来解决。数值结果验证了所提出的 DFRC 方案和相关算法的有效性。
Dual-function radar-communication (DFRC) design is a promising approach for solving the challenging spectrum congestion problem. This paper considers joint antenna selection and digital beamforming design for a DFRC system that serves multiple multicast communication groups and, meanwhile, performs sensing. The dual-function transmit design is cast as maximizing the minimum target illumination power in multiple target directions by jointly selecting the antennas and designing the beamformers subject to a lower bound on the signal-to-interference-plus-noise ratio (SINR) for the communication users and an upper bound on the clutter power at each clutter scatterer. The resulting optimization formulation is a mixed integer programming problem that is solved with a penalized sequential convex relaxation scheme along with semidefinite relaxation (SDR). Numerical results verify the effectiveness of the proposed DFRC scheme and the associated algorithm.
