Abstract
A sonar system to image the seabed, comprises at least one emission antenna to emit an acoustic beam covering a useful angular sector delimited by a first direction and a second direction, the distance between the antenna and the seabed being more significant in the first direction than in the second direction. The emission device is configured to form an emission pattern whose maximum is situated substantially in the first direction and which decreases from the first direction to the second direction and from the first direction in the sense opposite to the second direction, the energy attenuation being faster in the sense opposite to the second direction than toward the second direction.
