HYDROACOUSTIC RECEIVING MULTI-ELEMENTAL ANTENNA OF CONVEX DOUBLE CURVATURE FORM PLACED IN MEDIA BOW Russian patent published in 2017 - IPC H04R1/44 

FIELD: physics.

SUBSTANCE: antenna working surface is made in the form of three conjugate parts of circular barrels - bow and two side ones formed by sliding the generatrix - a circle arc of radius R_v along the guide representing three conjugate parts of circles of radii R_nos (the antenna nose) and R_bor (left and right sides of the antenna). Receiving channels in all current, defined by the number "m", horizontal planes parallel to the guide plane located on the circle arcs of the bow and side parts of the antenna in such a way that the ratio of the angular step channel location on the bow to the angular step on side parts is an integer.

EFFECT: creating the shape of the hydroacoustic antenna working surface, which allows to simplify the device for forming the directional characteristics and algorithms for processing signals received by the receiving channels, to reduce the costs for the hardware of the SAC.
