摘要

This paper proposes a joint design of transmit beam-forming and reconfigurable intelligent surface (RIS) reflecting for radar sensing and single-user communications. The radar receiving signal-to-noise ratio (SNR) is employed as a performance metric of target estimation which we aim to maximize while guaranteeing a pre-defined SNR for the user communication. The obtained problem is non-convex, and...
