The Application of the Time-delay and Bearings Localization Algorithm in the Underwater Target Tracking
Wang Shu-zong · Fire Control and Command Control · 2004
Passive localization algorithm is often used in the underwater target tracking.In this paper,the question of how to track underwater target using bearings and time-delay is presented and analyzed.The recursive least square(RLS)estimator is used to get target motion windage and used Kalman Filter(KF) to get target states by bearing and time-delay.The observer should be not making a maneuver during the course of tracking underwater target with bearing and time-delay.The simulation result confirms that the algorithm has a quick rate of convergence,lower localization error and stability.
