Reconfigurable intelligent surface (RIS) refers to a signal reflection surface composed of numerous low-cost passive reflecting elements. RIS can improve the performance of radar and communication systems by dynamically modulating the wireless channels. In this article, we consider the codesign for improving the coexistence between multiple-input–multiple-output (MIMO) radar and MIMO communication system with the assistance of RIS. The design objective is to improve the radar detection performance while ensuring reliable communication capabilities. The optimization problem associated with this codesign task is challenging due to the nonconvex nature resulting from the unimodular constraint on RIS coefficients and the constant-envelope constraint on the radar transmit waveforms. To address this problem, we propose a cyclic method that combines minorization–maximization, semidefinite programming, and alternating direction method of multipliers. Numerical examples are provided to validate the effectiveness of the proposed algorithm.
