Abstract
This paper investigates the problem of hybrid transceiver design for dual-functional radar-communication (DFRC) system. Specifically, we introduce an information embedding scheme for the DFRC system with a subarray structure. The hybrid transmit/receive beamformers are designed by maximizing sum-rate under constraints of power and similarity between the designed bemaformer and the reference one with good beampattern property. Since the formulated problem is difficult to tackle, we propose an alternating optimization method based on the alternating direction method of multipliers (ADMM) framework to obtain the hybrid beamformer. Numerical simulations are provided to demonstrate the effectiveness of the proposed schemes.
