Webimmediate feedback. There is a possibility that Curtin can provide a multibeam sonar (Reson 7125) for in-water biomass assessment or to directly image feeding whales, but the availability of this system is currently in discussion. The system will be deployed using a lifting gantry near the stern or over the side and towed off a stern quarter. WebTowed Underwater Video. The Camera-Based Assessment Survey System (C-BASS) is a towed underwater camera system custom built to non-lethally sample demersal reef fish and classify bottom types [46,47]. The C-BASS is towed behind a research vessel at speeds of 1.5–2 m s −1 and between 2–4 m above the seafloor [46].

PRINCIPLES OF SONAR BEAMFORMING - Curtis Tech

A towed array sonar is a system of hydrophones towed behind a submarine or a surface ship on a cable. Trailing the hydrophones behind the vessel, on a cable that can be kilometers long, keeps the array's sensors away from the ship's own noise sources, greatly improving its signal-to-noise ratio, and hence the effectiveness of detecting and tracking faint contacts, such as quiet, low nois… Unlike single beam sonar, which uses just one transducer to map the seafloor, a multibeam sonar sends out multiple, simultaneous sonar beams (or sound waves) at once in a fan-shaped pattern. This covers the space both directly under the ship and out to each side. Multibeam collects two types of data: seafloor … See more Computers on the ship collect these data and hydrographers process the data to create colorful two- or three- dimensional bathymetric (water … See more Multibeam sonar is useful for both water column and seafloor characterization.
