Abstract: Disclosed is a marine surface drone including: - an on-board multi-beam sonar; - a system for controlling the sonar, configured to command, for a given position of the drone, a plurality of consecutive transmissions of acoustic waves, the control system controlling the sonar transmitters so as to vary the characteristics of the transmitted acoustic waves, from one of the transmissions to the next, and - an acquisition unit configured to determine, from echo signals acquired in response to the plurality of transmissions, a three-dimensional image representing the content of a given observation volume. The invention also relates to a method for characterising an underwear environment, implemented by such a drone.
