Multibeam Sonar
An acoustic measurement technology that simultaneously emits tens to hundreds of sonar beams in a fan-shaped array to scan the seafloor on both sides of a vessel. The technique produces seabed topographic maps with centimeter-level resolution and is widely applied in marine surveying, underwater archaeology, and navigational channel investigation.
Timeline (last 90 days)
Multibeam sonar maps the shape and depth of the seafloor by emitting sound waves toward the seabed and charting the bottom topography based on the returning echo signals, then combining visualization technology to generate 3D imagery.
Single-beam sonar can only measure the depth of one point directly below at a time, whereas a multibeam system can simultaneously deploy a fan array of dozens to hundreds of sonar beams covering a width several times the water depth.
Multibeam sonar technology was originally developed by the navy for mine detection and channel surveying, and gradually became available to research and archaeological fields during the 1980s and 1990s.
