The problem of target detection in the clutter environment of millimeter-wave high-resolution radar is studied. A high-resolution polarization target detection method based on Stokes vectors is proposed. One-dimensional distance imaging is performed on the target using the radial high resolution inherent in the millimeter wave. Occupying the magnitude of the Stokes vector in the resolution unit interval and the fact that its polarization state changes greatly with respect to the amplitude of the Stokes vector in the resolution unit corresponding to the clutter and its polarization state, Vector two-threshold nonparametric detection method, the experimental simulation results show that this method can effectively improve the detection performance of the radar
