Underwater platform cluster cooperative passive detection multi-target track fusion method

Abstract

The invention discloses an underwater platform cluster cooperative passive detection multi-target track fusion method, which belongs to the technical field of underwater sound detection perception, and comprises the following steps: sorting multi-target data information passively detected by an underwater platform cluster to obtain track data of each target; according to the track data of each target, calculating the association probability of each track data so as to judge different platform detection tracks belonging to each target; detecting tracks based on different platforms of each target, calculating track quality of each track, setting a fusion threshold, and judging a target track needing to be fused according to the track quality and the fusion threshold; according to the passive detection performance of each underwater platform, distributing a track fusion static weight; and according to the track quality and the static weight of different tracks of the same target, carrying out dynamic weighted fusion on the tracks to form continuous tracks of each target. According to the method, the problem of association fusion of a few sparse or interrupted split tracks generated due to the influence of abnormal data and noise can be solved, and more comprehensive target track information can be obtained.
