【Abstract】 Millimeter wave MIMO integrated sensing and communication system is considered to simultaneously support multi-target sensing and multi-user communication. Firstly, we aim to minimize the matching error and cross-correlation of transmit beampattern by taking the millimeter wave geometric channel into account. The optimization is performed while satisfying constraints related to total power and multi-user signal to interference plus noise ratio requirements. Then, for the formulated joint beamforming design problem, we solve it using semidefinite relaxation to obtain the beamforming matrices for both sensing and communication functionalities. Finally, simulation results validate the effectiveness of the joint beamforming design.更多还原
