FIELD: hydroacoustics.
SUBSTANCE: method comprises comparing the measured value of sea noise with mean values. The output of the receiving unit of the hydroacoustic station provides the level of sea noise. The angle of inclination of the directional characteristic is set to be equal to the angle at which the value of the standard spatial spectrum for given region and season is equal to the mean spatial value. The angle of inclination of the directional characteristic should differ from this angle no more than by the width of the directional characteristic. The measurements are carried out throughout the spectrum with an increment that does not exceed the width of the directional characteristic, and the minimum of the measured values is determined.
EFFECT: enhanced precision.
