Title Research on underwater target tracking algorithm based on the bearings-only sensor array on the surface of water
Abstract Bearings-only target tracking is one of the most representative tracking methods in the field of target tracking。The underwater bearings-only target tracking has wide range of uses and attracts more and more attention。This paper is based on the sonar sensor on the water surface distribution。Using arrays’angular measurement information to realize the bearings-only passive tracking on the underwater target。First,the model of bearings only target tracking in uniform linear motion of the target is established。After that，the principle and concrete implementation steps of the Unscented Kalman filter (UKF)algorithm are given in detail。Finally,according to the target motion model and UKF algorithm, bearings-only target tracking model of the sonar sensor array is completed。By analyzing the simulation results about the application in underwater bearings-only target tracking and comparing tracking performance under different conditions,this method has better performance in target tracking accuracy, the convergence rate and stability of tracking。
