Ownship Strategies during Hostile Torpedo Attack


Background/Objectives: The necessity of ownship stratagies is essential during the attack of enemy torpedo. Methods/ Statistical Analysis: Torpedo tacking using advanced particle filter is proposed in bearings-only tracking environment for underwater applications. The observer platform has to perform evasive maneuver as well as perform target motion analysis to track the incoming hostile torpedo. Particle Filter (PF) combined with Modified Gain Bearings-Only Extended Kalman Filter (MGBEKF) is proposed technique. Findings: Monte-Carlo simulation is carried out for performance evaluation of the algorithm and the obtained results are presented which agree that PF-MGBEKF is most suitable as a part of ownship strategy.
