Source Localization by Maximizing the Longitudinal Correlation Using Waveguide Invariant Theory,ocalization error can be less than 10 % when the SNR at the beamformer output is more than 6–9 dB. It is also shown that this method is not suitable to estimate the range of source near the broadside of the line joined by the two array centers.

Sounds of Undersea Gas Leaks,s markedly different from the one of a free bubble. It was shown that the bi-spherical coordinates provide separation of variables and are most suitable for analysis of volume oscillations of constrained bubble. The theoretical model for the bubble volume oscillations near the seabed has been proposed and an analytical solution has been derived.

Research of Axis Mismatches Between Pairs of Sensitive Elements of Underwater Acoustic Velocity Gravelocity gradients are measured by underwater acoustic velocity gradient sensors and are derived while the axis mismatch exists, then the influences of measurement errors of underwater acoustic velocity gradient sensors by axial mismatches are analyzed.

A Passive Fathometer Technique for Bottom Profiling Using Ambient Noise,er, the nested vertical line array (N-VLA) was used for effective broadband beamforming, and the beamforming result for each sub-array was applied to the passive fathometer technique. The estimated results are presented here and compared to the sediment information obtained by chirp sonar profiles and coring analysis.

Inference of Sound Attenuation in Marine Sediments from Modal Dispersion in Shallow Water,ion from low-frequency acoustic field data include time-frequency techniques that make use of modal dispersion. Since modal separation improves as a sound signal that propagates to longer ranges, most of the inversion methods based on modal dispersion were carried out with long range data. Recently
