摘要
A system for detecting and locating submerged underwater objects having neutral buoyancy comprising mechanically steered sonar to image the water column comprises mechanically steered sonar with a single emission channel, to perform the insonification of a first individual sector in a first pointing direction by a single first acoustic pulse, the sonar forming a single reception channel suitable for acquiring a first acoustic signal resulting from insonification, the mechanically steered sonar being mounted on a carrier to advance in a main direction, the first pointing direction substantially lateral to the carrier and the first individual sector exhibits a wide relative bearing aperture and a narrow elevation aperture, the mechanically steered sonar comprising a mechanical pointing device to tilt the first pointing direction about an axis of rotation substantially parallel to the main direction allowing the sonar to acquire first acoustic signals resulting from insonifications performed in different pointing directions.
