Abstract

The application relates to an underwater target joint monitoring positioning tracking method based on an underwater acoustic communication detection integrated network, which comprises a target monitoring stage, a target positioning stage and a target tracking stage. In the target monitoring stage, all underwater integrated nodes send data packets in a numbering order to carry out neighbor discovery and topology establishment, and no-collision concurrent transmission constraints are established based on collected topology information; in the target positioning stage, three integrated nodes are selected from all underwater integrated nodes as a detection node cluster, and the detection node cluster completes positioning of the target by adopting a TOA algorithm according to received detection echoes reflected by the target; in the target tracking stage, a joint optimization model is constructed by taking minimization of a frame length and maximization of detection accuracy as targets, the joint optimization model is solved by adopting a simulated annealing algorithm, dynamic scheduling of node selection and a transmission sequence is carried out to complete tracking of the target. The application effectively improves network throughput, avoids data packet collision and shortens a frame length.
