ANORDNING FOR BEHANDLING AV MODULERTE SIGNALER MOTTATT AVET SIDESOEKENDE SONARSYSTEM

摘要

Device for the treatment of the echos backscattered by the surface of the seabed in response to the acoustic pulses transmitted by a fish towed immersed. / p & & p & it comprises at least one assembly d, d.. d for determining the components x and x of the complex envelope of the signals receipts by a reception chain 1 to 3 or a part of those - ci, obtained by selective filtering of a narrow band in the spectrum of frequency, and calculation means for memorisation and display 18 - 20 in order to obtain a representation of the variations as a function of time of the complex amplitude of the signals receipts. / p & & p & application to the sonar lateral in particular.
