Abstract (en)
[origin: WO2019122743A1] The invention relates to a marine surface drone (1) comprising: - an on-board multi-beam sonar (10); - a system (41) for controlling the sonar, configured to command, for a given position of the drone, a plurality of consecutive emissions of acoustic waves, the control system controlling the sonar emitters (12) so as to vary the characteristics of the emitted acoustic waves, from one of said emissions to the next, and - an acquisition unit (42) configured to determine, from echo signals acquired in response to said plurality of emissions, a three-dimensional image representing the content of a given observation volume. The invention also relates to a method for characterising an underwater environment, implemented by such a drone. Figure
