Acquirement and Application of Information During Guidance of Active Wake Acoustic Homing Torpedo

During the process of guidance, active wake acoustic homing torpedo can get the information about target orientation and the relative orientation of the torpedo and target by entering and leaving the wake. Further processing of this information will be beneficial to reducing endurance loss and increasing hit probability via the trajectory optimization, especially to coping with the countermeasures such as evading maneuver target and wake bifurcation by means of trajectory design. An algorithm to obtain and apply the information is proposed and verified by mathematical simulation.
