Torpedo guidance system

摘要

A dual mode guidance system for a torpedo includes a sonar sub-system 1, 2 for long range guidance and a 'close-in' sub-system including a laser beam generator, scanning means for scanning the beam over the target, and a processor 5 for analysing the laser return signals with a view to determining a best hit position on the target, say the mid-hull position of a submarine, and for then guiding the torpedo onto that position.
