| description | The invention relates to a sonar target tracking method, and especially relates to a passive sonar target tracking method. The method comprises the following steps: initializing parameters, including determining the number of particles, the metabolic rate and prior distribution of the particles, and setting the initial positions and states of the particles; calculating a particle space state set, a survival state set and a normalized weight set; carrying out resampling; and outputting a state estimation result. According to the passive sonar target tracking method provided by the invention, particle filtering and a tracking-before-detection algorithm are combined and applied to target tracking of passive sonar, the problems that a conventional algorithm often has false tracking, tracking loss, false alarm and the like in a complex low signal-to-noise ratio, strong interference and multi-target tracking environment are solved, and the tracking performance of equipment is improved.
