Ground Low-speed Moving Target Tracking Method for FMCW Radar Based on Inter-frame Plots-Centroid Algorithm

In this paper, the FMCW radar is installed above the prevention and control area to detect and track the ground low-speed moving targets in the area. Aiming at the problems of low ranging accuracy and data association failure in low-speed target tracking method based on intra-frame plots-centroid algorithm, an effective low-speed target tracking method based on inter-frame plots-centroid algorithm is proposed for FMCW radar. The algorithm adopts multi-frame merging processing, which improves the ranging accuracy and solves the problem of false alarms caused by multi-path effects. After practical engineering application, it is proved that this method has a great improvement in tracking results compared with the original method.
