Passive tracking method of distributed targets in wireless sensor networks based on potential game

摘要

In order to achieve the detection ability of distributed targets in wireless sensor networks, a passive tracking method of distributed targets in wireless sensor networks based on potential game is proposed. The distributed nodes of wireless sensor network are designed by uniform array distributed networking method, and passive tracking signals are collected in the link model of wireless sensor network. The feature of passive tracking signal is extracted by the method of fuzzy recognition. The potential game model is established, and the potential game objective function for passive tracking of distributed targets is constructed. Using the distributed target parameter estimation method, combined with signal detection and optimisation, the passive tracking and recognition of distributed targets in wireless sensor networks are realised. The simulation results show that the method has high accuracy and parameter identification accuracy for distributed target tracking, and improves the tracking and detection ability.
