Generalized Mixture Noise Models for U.W.A.tection. Its performances are based in part upon the noise modelling [1]. The usual assumption of a white Gaussian noise is not valid [2].

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作者: 音的強(qiáng)弱 時(shí)間: 2025-3-23 06:34
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.作者: Aggrandize 時(shí)間: 2025-3-23 12:31

The Multipath Coherence Function for Correlated Random Channels and a Moving Sourcessing. The Mutual Coherence Function, which is the normalized cross spectral density, is normally used to characterize the spatial coherence of the sound field.

Vertical Directionality of Ambient Noise at 32 ° N as a Function of Longitude and Wind Speedal differences in the vertical distribution of noise have been measured, especially at the higher frequencies which can be interpreted in the context of attenuation by seawater sound absorption of coastal shipping.
