Analysis of signals spectrum in the shallow sea

In the shallow waters any acoustic field is the super-position of running and standing waves. The report under consideration offered some results of stringent solution of Helmholtz´s equation taking into account actual parameters of bottom ground, marine water and surface. This algorithm admits to calculate dispersion of pressure, oscillation velocity and stream of energy in every point of a closed space including the space near surface. The results of mathematical exploration of array´s field that arose from 20 elements in closed volume, distribution of the group velocity, energy transfer inside marine bay are displayed. These results of digital research are compared with the experimental testing performed at the Peter the Great Bay (Japan Sea).
