1. Способ определения чувствительности гидроакустической антенной решетки в лабораторных условиях, заключающийся в расположении калибруемой антенной решетки в гидрокамере с размещенными в ней опорным гидрофоном и гидроакустическими излучениями, расположенными вдоль гидрокамеры, формировании в гидрокамере с помощью излучателей акустического поля, моделирующего поле плоской волны, и измерении выходных сигналов антенной решетки и опорного гидрофона, по которым определяют чувствительность антенной решетки, отличающихся тем, что с помощью излучателей по всей длине гидрокамеры формируют акустическое поле, моделирующее падающее на антенную решетку поле плоской волны с углом падения равным нулю.1. A method for determining the sensitivity of a hydroacoustic antenna array in laboratory conditions, which consists in arranging a calibrated antenna array in a hydro chamber with a reference hydrophone and hydro-acoustic radiation located along the hydro chamber, forming an acoustic field in the hydro chamber with emitters simulating a plane wave field, and measuring the output signals of the antenna array and the reference hydrophone, which determine the sensitivity of the antenna array, characterized in that with schyu emitters along the entire length gidrokamery form acoustic field simulator incident on an antenna array plane wave with an angle of incidence equal to zero. 2. Способ по п.1, отличающийся тем, что моделирующее падающее на антенную решетку поле плоской волны с углом падения равным нулю удовлетворяет математическому соотношению
