Target control system for steered torpedo - uses acoustic target location data and switches from navigation mode to curved steering mode at given proximity

摘要

The control system uses acoustic target location data allowing the steering to be switched from a given course or a proportional or target area navigation mode to a curved steering mode. The switch on is effected at a given proximity (A) to the target, determined from the remaining time for the torpedo (To) to reach the target point (P). The steering angle for the curved steering path is pref. proportional to the target angle at the switch on point.
