This invention relates to a beamforming method for an integrated communication and sensing system assisted by an intelligent reflective surface, belonging to the field of wireless communication technology. The method first synthesizes multiple beams for multiple communication users and radar targets using spatial degrees of freedom, based on the transmit beamforming design requirements. Then, by jointly optimizing the transmit beamforming of the base station and the phase shift matrix of the RIS (Radio Response System), the beamforming design method is expressed as a constrained optimization problem for solution. Under the constraints of signal leakage-to-noise ratio and RIS phase shift, the performance of MIMO radar transmit beamforming is maximized. Finally, the solution is obtained through an alternating iterative optimization method. The joint beamforming method of this invention is simple to implement, has a wide range of applications, and can improve the spectral efficiency of integrated communication and sensing systems.
