In order to improve the transmission security of millimeter wave in radio frequency(RF)transmission,the research on 5G millimeter wave RF algorithm in multi-input multi-output(MIMO)radar search mode was proposed.Based on the transmission characteristics of 5G millimeter wave,the radar interception factor of MIMO radar search mode was obtained.A millimeter wave radio frequency stealth model was established and the objective function was obtained.The radio frequency interception probability of the radar search mode was calculated.The best estimation value of millimeter wave RF channel was obtained by combining the millimeter wave channel sparsity results with Bayesian algorithm,from which the best value of RF channel was calculated,and the RF transmission was realized by using the estimated signal transmission after stealth.The experimental results show that when the millimeter wave RF transmission time is 140 s,the ρ of the proposed method is as high as 0.83.It is proved that when this method is used for millimeter wave RF transmission,the transmission quality of millimeter wave is high,the phase amplitude deformation is not easy to occur,and the high-quality transmission of 5G millimeter wave RF can be realized.
