Abstract
The feasibilities of the usage of large aperture stationary arrays for the acoustic observation of the northwest part of the Pacific ocean existing near the Kamchatka peninsula are described. Such an array has a plane aperture filled with 2400 hydrophones and allows the monitoring of ocean noise distribution in a horizontal view sector of 120 deg within a frequency range up to 1400 Hz. Reconstruction of ocean noise sources distribution over the ranges up to about 1000 km from a shore can be made by a method of emission acoustic spectrotomography. Spatial resolution can be improved by the incorporation of several arrays for observation. Acoustic large-scale vision may be applied for the monitoring of wind distribution, in particular storms.
