FIELD: hydro acoustics.SUBSTANCE: invention relates to hydroacoustics and is intended for determination of parameters of noisy objects in sea. Proposed device comprises multi-element acoustic receiving antenna hydrophone, unit for generating sheaf of directivity characteristics in horizontal and vertical planes, band-pass filtering unit, detector, accumulator, unit for calculating signal/noise ratio, unit for detecting objects with determination of direction, is supplemented with new units, namely of matrix measurement, unit for measuring vertical incision of sound speed, unit for calculating field, generator matrix forecast grid distance-depth, generator of two-dimensional function measures of similarity, joint unit of depth and distance determination, unit for determining noisiness of object.EFFECT: technical result is upgraded accuracy of estimating noisiness of object and determining complete set of information on noisy in sea object (direction onto object, distance to object, class noisiness of object, depth of immersion of object) in one device.1 cl, 1 dwg |
