Blending underwater acoustics and acoustical oceanography
The Journal of the Acoustical Society of America, 2007Acoustical oceanography, which is the use of sound to probe ocean processes, had been in practice for many years before Hank Medwin spearheaded the creation of the ASA Acoustical Oceanography Technical Committee (AOTC). It has blossomed since that time, aided by interactions fostered by AOTC activities.

RAY CHAOS IN UNDERWATER ACOUSTIC WAVEGUIDES
International Journal of Bifurcation and Chaos, 2008The chaotic motion of a ray path in a deep water acoustic waveguide with internal-wave-induced fluctuations of the sound speed is investigated. A statistical approach for the description of chaotic rays is discussed. The behavior of ray trajectories is studied using Hamiltonian formalism expressed in terms of action-angle variables.

Bidirectional equalization for underwater acoustic communication
The Journal of the Acoustical Society of America, 2012The bidirectional decision feedback equalizer (BiDFE) that combines the outputs of a conventional decision feedback equalizer (DFE) and backward DFE can improve the performance of the conventional DFE by up to 1–2 dB based on simulations. In this letter, the BiDFE concept is extended to multichannel time reversal communications involving a DFE as a ...
