Radar target data association method and device, equipment and storage medium

Abstract

The invention discloses a radar target data association method and device, equipment and a storage medium, and the method comprises the steps: obtaining signal structure information corresponding to a first reference point and signal structure information corresponding to a second reference point, the first reference point being obtained according to first frame echo data, and the second reference point being obtained according to second frame echo data; inputting the signal structure information corresponding to the first reference point and the signal structure information corresponding to the second reference point into a similarity determination model to obtain a similarity value between the first reference point and the second reference point; and if the similarity value is smaller than or equal to a preset similarity threshold value, determining that the first reference point and the second reference point are the same targets. In the data association process, the structure information of the target echo signal is fully considered, the obtained similarity value is more accurate, and the correct association probability of the target is improved.

Description

technical field [0001] The invention belongs to the technical field of radar, and in particular relates to a method, device, equipment and storage medium for radar target data association. Background technique [0002] Object tracking is used to associate the same object from the environment where noise and clutter exist. In the initial stage of target tracking, target tracking can be carried out by data association, that is, the target track can be extracted from the echo data of multiple consecutive scans without introducing too many false tracks. [0003] The traditional method of target tracking is mainly designed based on the uniform motion model of the target, that is, the sequential processing method and the batch processing method assuming that the target is moving at a uniform speed. [0004] However, in practical applications, if the target maneuvers, that is, it does not move at a uniform speed, using the above method will easily cause model mismatch, and the acc...
