Beschreibung
Zusammenfassung:	An underwater vehicle provided with a sonar for detecting underwater objects, the sonar being a sonar whose angular coverage in elevation is comprised between 45 and 240 degrees, is oriented towards the surface when the underwater vehicle is in the detection phase of an underwater object and whose angular coverage in bearing is less than 10 degrees to obtain measurements in a plane, all the measurements of a plane being obtained in one emission/reception cycle, the sonar allowing the detection of underwater objects located at a depth less than that of the underwater vehicle.
