Abstract
Способ анализа акустического поля сложного источника, включающий синхронный многоканальный прием гидроакустических сигналов при помощи дискретной антенны из эквидистантных приемников, полосовую фильтрацию принятых сигналов в каждом канале, умножение мгновенных частот принятых сигналов на число приемников в дискретной антенне, суммирование принятых сигналов, суммирование сигналов с умноженными мгновенными частотами, амплитудное детектирование суммарных сигналов, перемножение результатов детектирования и регистрацию результирующего сигнала после перемножения продетектированных сигналов, отличающийся тем, что после фильтрации принятые сигналы запоминают и многократно воспроизводят с ними операции способа, причем в каждом цикле воспроизведения принятые сигналы и сигналы с умноженными мгновенными частотами задерживают в каждом канале на время распространения акустической волны от контролируемой точки поля до соответствующего приемника дискретной антенны, после чего осуществляют регистрацию результата известным способом.A method for analyzing the acoustic field of a complex source, including synchronous multichannel reception of hydroacoustic signals using a discrete antenna from equidistant receivers, band-pass filtering of received signals in each channel, multiplying the instantaneous frequencies of the received signals by the number of receivers in the discrete antenna, summing the received signals, summing the signals with multiplied instant frequencies, amplitude detection of the total signals, multiplication of the detection results and registration of the resulting signal after multiplying the detected signals, characterized in that, after filtering, the received signals are stored and repeatedly reproduce the method operations with them, and in each playback cycle, the received signals and signals with multiplied instantaneous frequencies are delayed in each channel for the duration of the propagation of the acoustic wave from the controlled field point to the corresponding discrete antenna receiver, after which the result is recorded in a known manner.
