Abstract

Background/Objectives: This paper presents parameterized Modified Gain Bearings Only Extended Kalman Filter to track a torpedo using bearings-only measurements. Methods/Statistical Analysis: The parameterization is included to obtain fast convergence in estimated torpedo motion parameters. Findings: Observer uses estimated target kinematics to determine proper observer manuever calculates. Monte-Carlo simulation is carried out and the results are presented. Application/ Improvements: It is noted that parameterization reduces the time of convergence and the results are satisfactory.
