ud11-30 – APPLICATION: This invention is a method to
track a fluid of different acoustic index of refraction, within another fluid,
using the broadband acoustic signal transmission in frequency bands of 10’s –
100’s of Hz.
methods used to detect underwater acoustics in low frequency have not been
extensively tested on a large scale. Additionally, most of these... Read More
ud10-25 – APPLICATION: This is a method and system for locating
the position and trajectory of an object moving under the surface of water in
coastal area using acoustical signals.
PROBLEMS ADDRESSED: Current underwater positioning systems are unable to accurately measure the
position of objects over 10 km. This system uses low frequency in shallow water
which can transmit signals over 2500... Read More
