Close-range speed correction method and device of radar, radar and storage medium

The invention is suitable for the technical field of radars, and provides a short-distance speed correction method and device of a radar, the radar and a storage medium. The method comprises the following steps: after a radar transmits a signal, acquiring an echo signal, and obtaining a point cloud of a dynamic target according to the echo signal; the point clouds are clustered, clustering points of the dynamic target and corresponding clustering information are obtained, and the clustering information comprises the speed of the dynamic target relative to the radar; acquiring a historical track, and determining a target track associated with the clustering point of the dynamic target in the historical track; and adjusting the speed of the dynamic target relative to the radar according to the target track to obtain the correction speed of the dynamic target relative to the radar. The method can improve the speed measurement precision of the dynamic target (target vehicle) under the short distance condition, re
