Non-cooperative vessel tracking to assess potential threats is becoming increasingly important to the defense of the U.S. coastline and ports of entry; so there is a need to identify and intercept potential threats well before they reach our shores. To support this critical surveillance activity the… More

The U.S. Navy desires the use of Unmanned Surface Vessels in littoral water regions for the mission of Mine Counter Measures. In particular, the use of the standard Navy Rigid Hull Inflatable Boats (RHIBs) for such a mission is desirable to decrease dependence on traditional, high operating cost… More

The U.S. Navy has researched the use of various acoustic sensing technologies that exploit the deep water reliable acoustic path (RAP) using vertical line arrays (VLA's) of vector sensors with success. The buoys used were, however, large, over-the-side deployed, research systems to demonstrate the… More

The Navy desires the use of RHIB's in littoral waters for MCM because of its many advantages. However, these advantages can only be accomplished by providing a towed minesweeping approach that allows the RHIB to adequately perform the required mission within its limited towing capacity. The Phase I… More

Energy extraction is needed for various ocean deployed devices. Extracted energy can be expected to be at various levels and intermittent, but plentiful. The Phase I effort will recommend an extraction technique that directly converts ocean energy into electrical power. The extractor will be… More

The frequency spectrum of interest for hydrophones used in Naval tactical systems, ocean surveillance systems, or for environmental monitoring is continuing to expand, due to increased interest in passively detecting third-world submarines, merchant shipping, biologics, etc. as well as increased… More

Undersea tracking ranges are used to monitor and assess the performance of submarines, torpedoes, ships and targets conducting tests and exercises on weapon system performance. The ability to track these platforms is largely based on the performance of the transducers used in the tracking systems.… More

Although the performance of naval systems for Anti-Submarine Warfare and Counter-Torpedo Detection, Classification, and Localization systems are presently adequate for current missions they are limited by the size, power and detection range of the associated sonar transducer arrays. What is required… More
