SHIP HYDROACOUSTIC STATIONS REPAIR AND MODERNIZING

Authors: Shamarin I., Iezhel M., Savina I., Alekseenko A. In the article there is the short characteristics of hydroacoustic equipment which is represented on Ukrainian, Russian and other naval ships. The optimal lines of hydroacoustic stations modernizing, which can provide the improvement of warships performance characteristics, are considered in this article. The article is published in the Science-industrial Journal "ARSENAL-XXI" №3-4, 2009. Kyiv, Ukraine. (E-mail:arsenal-2137@list.ru).

HYDROACOUSTIC AUTONOMOUS ANCHOR STATION

Authors: Shamarin I., Shamarin A., Boretskyy A., Alekseenko A. The constructive building and the functional features of the hydroacoustic autonomous anchor station are thoroughly viewed in this article. Such station is aimed to reveal underwater objects by using vector-phase methods of signal processing. The article is published in the Science-technical Journal "Technological Systems" N 3(47)/2009. Kyiv, Ukraine.

VECTOR-PHASE METHODS IN HYDROACOUSTICS

Authors: Shamarin I., Shamarin A., Savina I., Alekseenko A. The article deals with one of the ways of vector-phase methods realization sn Hydroacoustics used for the analyses of the water area acoustic state made by means of registration and consequentprocessing of the wave pressure from the underwater object and of three projections of fluctuating speed vector. The article also presents the constructive scheme of vector-phase antenna building and the physical algorithm of its functioning. The article is published in the Science-technical Journal "Technological Systems" N 3(47)/2009. Kyiv, Ukraine.
