Parametric Sonar Development
The Office of Naval Research together with the Naval Sea Systems Command have invested
millions of R&D dollars to improve sonar system performance on Navy destroyers
and cruisers that must now—since the end of the cold-war—be focused
on conducting shallow water operations against hostile undersea tactics such as
deployed sea mines, underwater improvised explosive devices (UWIED), and quiet diesel-electric
submarines.
This ongoing sonar development is necessary because maintaining a complete awareness
of the undersea threat environment is as much a key element to protecting sailors
and warships from harm’s way as is the continuous surveillance against surface, air,
and space-borne threats.
As sea-based carrier and expeditionary strike groups carry out their missions to
project power and provide forward presence in coastal areas around the world, their
ability to maneuver anytime and anywhere with impunity requires specialized sonar
systems that are up to the task of efficiently operating in a complex littoral battle-space
filled with acoustic noise and reverberation.
Parametric sonar is one of the proven active acoustic technologies developed and
evaluated by the US Navy to demonstrate specific performance improvements that can
enhance combat effectiveness for conducting missions in these shallow water areas
that are sometimes too challenging for conventional echo-ranging capabilities.
GP Strategies is committed to using our unique expertise in this field to team with
interested developers who will pursue widespread commercial adaptations of the Navy’s
investment.
Transitioning the versatile power of parametric sonar technology into practical
spin-off uses opens up the possibility of implementing solutions for homeland security
port/harbor underwater defense needs, ocean floor exploration, and secure undersea
acoustic communication applications.
