Simultaneous Radar Sensing and Communication Enabled by Joint Transmit-Receive Beamforming

This paper investigates the dual-function realization problem for the integrated radar-sensing and communications (IRSC) system. The freedom degrees of design are the transmit and receive beamformers. Firstly, the design problem is formulated as a sensing signal-to-noise ratio (SNR) maximization problem with the constraint of sidelobe level (SLL). Secondly, the formulated non-convex problem is solved through a sequential optimization algorithm that jointly optimizes the transmit and receive beamformers. Finally, simulation results are given to demonstrate the effectiveness of the proposed algorithm and its superiority over the existing algorithm in terms of the symbol error rate performance.
