Abstract
Disclosed is an echosounder configured to: a) drive the transducers of its emitting antenna to emit first and second acoustic waves having first and second frequencies, these waves being superposed over one another along an axis of superposition that is directed toward a point of the bottom of the subaquatic environment, and b) acquire an echo signal, the frequency of which is equal to the difference between the first and the second frequencies, the echosounder being configured to perform steps a) and b) a plurality of times while varying the orientation of the axis of superposition, and to determine, on the basis of the acquired echo signals, an image representative of the content of the sub-bottom of the subaquatic environment beneath each of the points. Also disclosed is an associated method for characterizing a portion of the sub-bottom of a subaquatic environment.
