Abstract
This paper considers beamforming design for analog array architectures in an integrated sensing and multi-user communication system. Particularly, addressed to the ISAC challenges stemming from the full-duplex operation, the proposed method suppresses the self-interference (SI) and enables co-existence of multiple simultaneous beams for both communications and sensing purposes. The proposed analog beamformers maximize the beamforming gain at the sensing direction while maintaining beamforming gain at the communications direction(s), as well as mitigating the potential reflection from the environment by optimizing the low-sidelobe combined radar pattern. Simulation results demonstrate the effectiveness of the proposed method in terms of gain, sidelobe level, SI cancellation and sensing performance.
