In recent years, spectrum congestion has become a significant issue. Thus, significant attention has been paid to spectrum-sharing. The dual-function radar-communication (DFRC) system is an attractive solution for the spectrum-sharing problem. Existing studies primarily focus on transmitted beamforming at the base station (BS). In this study, we designed both the transmitted and received beamformers of a DFRC BS to perform multiple-input multiple-output (MIMO) radar sensing and multi-user multiple-input single-output (MU-MISO) communication employing hybrid beamforming. To address the difficulty of the primal problem, we recast the nonconvex design problem into a convex form and subsequently derive suboptimal solutions. Simulation results demonstrate satisfactory performance in terms of the sum-rate, interference mitigation, desired signal enhancement, and complexity of the proposed scheme.
