HYDROACOUSTIC AERIAL Russian patent published in 2009 - IPC G01S7/52 H04B13/02 

FIELD: physics.

SUBSTANCE: invention concerns area of hydroacoustics and can be used at manufacturing of conformal aerials with a surface having sites of double curvature. The hydroacoustic aerial of the convex shape contains a form-building skeleton with sites of double curvature. The hydroacoustic receivers screened on a back surface are mounted on the aerial. Receivers are structurally interfaced with lines of electric communications in the flexible linear reception modules consisting of set of receivers. The modules are pinned to a form-building skeleton of the aerial uniformly on all length. Flexible receiving modules are located on lines of crossover of planes, perpendicular axes of symmetry of a surface of a form-building skeleton, with its surface. Each hydroacoustic receiver is fixed on a skeleton so that the axis of its characteristic of an orientation has been focused perpendicularly aerial surfaces.

EFFECT: improvement of symmetry of the main maximum of the characteristic of aerial orientation, decrease in size of additional maxima and increase of factor of aerial concentration.
