The Influence of Bubbles on Acoustic Propagation and Scattering screening of the sea surface due to bubble clouds with increasing frequency and sea state. The excess attenuation decreases with increasing depth below the surface and shows extremely high values within bubbles clouds.

Generalized Mixture Noise Models for U.W.A.tection. Its performances are based in part upon the noise modelling . The usual assumption of a white Gaussian noise is not valid . Progresses in implementation appear to make possible the use of non-Gaussian noise models .

Low Frequency Sector Scanner Using NLA array. The drive waveform for each amplifier is computer generated which allows a considerable amount of flexibility in the use of the transmitter. (Ref. 1) One possible mode of operation is to use the non-linear effect in the water to produce low frequency signals. Such a system has been tested re

Acoustic Coherence Loss Due to Ocean Boundary Interactionsdary. Another is the spatial loss due to multipath in both constant-depth and variable-depth water, noting that for an array at the top of a slope it may largely be avoided by laying along the contours.
