Abstract

FIELD: detection and determination of coordinates of noise sources. SUBSTANCE: signals are received by means of several motionless directed aerials. Spatial-frequency filters are formed and spectrum is subject to analysis at points of mutual crossings of spatial channels of several aerials. Areas to which the signal belongs and coordinates of their sources are determined by means of calculation of derived noisiness. EFFECT: improved precision.

Изобретение относится к гидроакустике и позволяет обнаруживать и определять координаты источников шумовых сигналов в море в условиях их большого числа в ограниченном пространстве. С помощью нескольких неподвижных направленных антенн осуществляют прием сигналов, формируют пространственно-частотные спектры, анализируют спектр в точках взаимных пересечений пространственных каналов нескольких антенн и с помощью расчета приведенной шумности определяют принадлежность сигналов и координаты их источников.The invention relates to hydroacoustics and allows to detect and determine the coordinates of the sources of noise signals in the sea in the conditions of a large number in a limited space. Using several fixed directional antennas, they receive signals, form spatial-frequency spectra, analyze the spectrum at the points of mutual intersection of the spatial channels of several antennas and determine the affiliation of the signals and the coordinates of their sources by calculating the reduced noise.
