Abstract:

A proposed hull-mounted pro-submarine torpedo countermeasure is examined, which is an adaptation of an NRL-developed countermeasure against tracking radar systems. This device should be effective against all known types of active acoustic homing torpedoes and, modified, possibly against passive acoustic torpedoes. Its operation is based on the fact that the apparent position of any finite target of complex structure, as seen by a tracking system, will wander about the physical center of the target. This natural phenomenon is exploited by the countermeasure device so that the echo returned to the tracking system appears to come from a location many target spans away from the target. Preliminary experimental data indicate the feasibility of this technique as applied to sonar.
