The invention discloses a foundation surveillance
radar multi-target tracking method based on
radial velocity information. The foundation surveillance
radar multi-target tracking method based on
radial velocity information includes the following steps: S1, calculating the track fitting degree by means of
radial velocity; S2, generating
hypothesis by means of the radial velocity fitting degree andthe positional information; S3, modifying the track scores of the first k optimal
hypothesis by means of the radial velocity fitting degree, and obtaining the
hypothesis probability pj of each hypothesis in the first k optimal hypothesis; S4, establishing a hypothesis tree according to the first k optimal hypothesis, based on the principle of selecting the root node in which the hypothesis probability pj is, performing
pruning on the hypothesis tree by means of an N
pruning algorithm, and leaving the optimal hypothesis to be determined; and S5, according to a preset determination threshold T1and a preset delete threshold T2, comparing the track scores of the optimal hypothesis to be determined in the step S4 with the determination threshold T1 and the delete threshold T2, so as to determine the track or delete the track. The foundation surveillance
radar multi-target tracking method based on radial velocity information can realize inhibition of false tracks and
false alarm in a strongclutter and high
false alarm environment, and can greatly improve the radar multi-target tracking effect.
