SUBMARINE HYDRO ACOUSTIC SYSTEM ANTI-TORPEDO PROTECTION SYSTEM

摘要

FIELD: shipbuilding; hydro acoustics.;SUBSTANCE: invention relates to the submarine self-defense hydro acoustic means. To solve the tasks set in the anti-torpedo protection system, two identical receiving and radiating antennas are used, having the semi-cylindrical opening and representing the phased antenna arrays with possibility of the scanned in vertical and horizontal planes directional characteristic (DC) in the radiation mode formation and the DC static fan in the reception mode formation, as well as receiving antenna, forming the four-beam DC, forming the cross in cross-section by the horizontal plane and oriented to the upper hemisphere.;EFFECT: technical results from the use of the proposed submarine hydro acoustic system anti-torpedo protection system are increase in the coverage sector in horizontal plane to 360° and possibility of the splashing rocket-torpedoes and aviation torpedoes detection in the upper hemisphere.;1 cl, 1 dwg
