In this paper, a dual-RIS assisted ISAC system is proposed to achieve high-precision accurate positioning of users in the uplink transmission and the optimal beamforming design of the BS and RISs is presented based on the positioning information. The proposed ISAC system realizes the sensing and communication under the same frequency and timeresources. It is verified through simulation that the presented SMP algorithm has excellent positioning performance and the near-optimal system achievable rate can be achieved with the optimal beamforming design of the BS and RISs.
