In the paper, the system framework you described uses both LiDAR and millimeter-wave radar data for UAV trajectory tracking. However, I don't see millimeter-wave radar data being used in the code. Why is that? Also, in the fusion_tracking code file, the reorg_data folder is used. Where does the data in that folder come from?
