International audience; Real time service and synchronization are very important to many underwater systems. But the time service and synchronization in existence cannot work well due to the multi-path propagation and random phase fluctuation of sign

Using the parabolic equation code RAM, the sound field vertical correlations are studied as functions of vertical spans and ranges in sloping bottom environments. The wedge mode theory is used to explain the numerical results. It is shown that there

Low‐frequency (LF) sound speed and attenuation in sandy/silty seabottoms have recently been analyzed and summarized from long‐range field measurements in shallow water [Zhou, Zhang and Knobles, J. Acoust. Soc. Am., 125, 2847–2866, 2009]. Field

Internal waves are one of the most pronounced oceanic phenomenons to the oceanographer. During past decades much effort has been made to investigate the effect of internal waves on shallow water acoustic propagation. Even though many field observatio

Although the ocean environment in shallow water is very complex, there still exists stable interference pattern for broadband low frequency sound propagation. The waveguide invariant concept is introduced to describe the broadband interference struct

Due to the high resolution of time reversal processing in a shallow water waveguide, the target can not be treated as a point‐like scatterer, but should be modeled as a distributed target composed of elemental scatterers. In this paper, the problem

At frequencies of about 1 kHz and higher, forward scattering from a rough sea surface (and/or a rough bottom) can strongly affect shallow water propagation and reverberation. The need exists for a fast, yet accurate method for modeling such propagati
