Work: Statistical characteristics of acoustic signal in marine environment and the signal-to-noise ratio at linear equidistant acoustic antenna. Technical university of Radiotechnics, Electronics and Automation.

Main results: Analytical expressions of the signal-to-noise ratio are obtained for the antennas placed in the random acoustic wave field. Algorithms are elaborated for it's calculation by PC. Results are obtained which can be used for the approximate value of the expansible correlation intervals of the sound field in an ocean. These results allow to solve the problem of the optimum choice of a length of the underwater acoustic antenna both vertical and horizontal. The analysis for solution of the problem to underwater sound of propagation in a typical ocean condition is given, and the conclusions for the technique of solution this problem developed by stochastic equations of Dyson, Bethe-Salpeter are done. Subsequently, investigation of characteristics of the space-time variations of the sound fields in an ocean and investigation of peculiarities this characteristics in a shelf zone will be developed (the record of the sound signals is used in realistic conditions). The value of possible increase of the effect of technical control means of an aqueous space will be obtained by the upper characteristics calculation of the sound fields variations.
