Semi-practicality Simulation of Underwater Multi-target Tracking System

Aiming at the whole process of underwater multi-target tracing, the model of multi-target ocean environment was constructed, and the model and simulation method of multi-target localizing and tracking were also presented. A novel semi-practicality simulation method was brought out. The simulation of maneuvering multi-target was realized in water-tank with the static long line arrays and multi-target signal sources by the proposed method. The multi-target tracking algorithm was implemented by the DSP system. The typical simulations of tracking multi-target were carried out. The results show the proposed system can reflect the details of real underwater multi-target tracking as well as the high performance in precision, and provide groundwork for the practicable implementation of multi-targets localization and tracking in underwater environment.
