摘要：

The definition of the concentration coefficient of a hydroacoustic array in a waveguide was analyzed. The acoustic field produced by the array is symmetric in the horizontal plane. The excitation distribution specified on the aperture of the vertical array is a sum of weighted eigenfunctions of the normal waves propagating in the wavefield. The horizontal concentration of the acoustic energy produced by the array in the waveguide was determined. The array operates at low frequencies and a small number of normal waves can propagate, for which the acoustic field emitted by the array is nondirectional.
