[0029] In order to improve the multi-target tracking accuracy and tracking speed of millimeter-wave radar in practical applications, the present invention proposes a multi-person tracking and counting method based on millimeter-wave radar. The method first generates points from the radar data cube (Data Cube) Cloud data, and then perform agglomeration operation on the point cloud data to obtain the agglomeration points, perform neighbor clustering on all trajectories of the current frame, distinguish easy-to-handle trajectories from difficult-to-handle trajectories according to the clustering results, and use complex The data association algorithm is used for tracking; for the tracks that are easy to handle, a simple data association algorithm is used for tracking; the corresponding track is started and terminated according to the data association situation, and the result of multi-person tracking is finally obtained.
