Objective: This paper presents the interacting multiple model (IMM) method of tracking underwater maneuvering targets using active sonar measurements.Methods: The IMM algorithm is a widely accepted state estimation scheme for solving maneuvering target tracking problems.Results: In the underwater scenario, algorithms that assume constant velocity model are suitable for tracking nonmaneuvering targets but fail if target is maneuvering.Conclusion: Unscented Kalman filter is used throughout the process, and the simulation results for two scenarios are presented.
