Abstract

A synthetic aperture acoustic underwater antenna comprises an assembly (10) of electro-acoustic transducers which is supported on the sea bed and rotates at constant angular velocity in a fixed circular path. The assembly is connected by a cable (23) to an above-water signal processing unit (22). In a further embodiment rotation is achieved by selective switching of a circular array of transducers. The device may be used in offshore technology e.g. drilling site supervision and sea-bed prospecting. It may also be used for harbour and sea-lane traffic control. <IMAGE>
