ABSTRACT:
A device for processing echoes back scattered from the surface of the sea bed in response to sound pulses transmitted by a fish towed while immersed, comprising at least one assembly for determining the components X.sub.C and X.sub.S of the complex envelope of the signals received by a reception chain or from a part thereof, obtained by selective filtering of a narrow band in the frequency spectrum, and computing, storage and display means for obtaining a representation of the variations in time of the complex amplitude of the signals received.
