Abstract
A device for transmitting acoustically toward the bottom of the sea includes an arrangement of a cable 404 containing vertically suspended electro-acoustic transducers 403 wherein each of said transducers are assigned to a frequency of the pulse spectrum to be emitted. The transducers are attached to the cable at such positions whereby the wave transmitted toward the sea floor is in phase with the reflective wave on the surface of the sea The superimposition of different elementary signals constitutes a single strong pulse. The device replaces air gun devices for oil exploration.
