  • Acoustic scattering from double-diffusive microstructure 

    Lavery, Andone C.; Ross, Tetjana (Acoustical Society of America, 2007-09)
    Laboratory measurements of high-frequency broadband acoustic backscattering (200–600 kHz) from the diffusive regime of double-diffusive microstructure have been performed. This type of microstructure, which was characterized ...
  • Calibration of broadband active acoustic systems using a single standard spherical target 

    Stanton, Timothy K.; Chu, Dezhang (Acoustical Society of America, 2008-07)
    When calibrating a broadband active acoustic system with a single standard target such as a sphere, the inherent resonances associated with the scattering by the sphere pose a significant challenge. In this paper, a method ...
  • Smoothly modulated frequency-bounded impulse signals for tomography 

    Duda, Timothy F.; Lynch, James F. (Woods Hole Oceanographic Institution, 1991-06)
    A group of amplitude and frequency modulated signals which generate narrow synthesized pulses and which also have smoothly varying phase are described. The frequency-sweep (chirp) signals have exactly-defined frequency ...
