  • Design and testing of an acoustic ultra-short baseline navigation system 

    Tracey, Brian H. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1992-09)
    An ultra-short baseline acoustic navigation system has been developed which is capable of determining bearing to a sound source with an error of less than 1° in typical operational conditions. The system has a demonstrated ...
  • An integrated modal approach to surface and volume scattering in ocean acoustic waveguides 

    Tracey, Brian H. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1996-01)
    Acoustic propagation in the ocean can be strongly affected by small random variations in ocean properties, including rough surfaces and volume fluctuations in the ocean or seabed. Such inhomogeneities scatter part of the ...
