Side-scan sonar (also sometimes called side scan sonar, sidescan sonar, side imaging sonar, side-imaging sonar and bottom classification sonar) is a category of sonar system that is used to efficiently create an image of large areas of the sea floor.

Side-scan sonar is a category of active sonar system for detecting and imaging objects on the seafloor. The multiple physical sensors of the sonar — called a transducer array — send and receive the acoustic pulses that help map the seafloor or detect other objects.

2021年2月10日 · Marine Sonic Technology (MST) is a leading provider of ultra-high-resolution side-scan sonar systems for any application. Our Sea Scan® product line is one of the most advanced in the world for underwater imaging.

Sidescan sonar is an acoustic survey device which is used in underwater imaging. It is most commonly used to image marine substrates. For example sidescan is used for mapping sub-sea geological features, corridor or hazard surveys for pipeline and cables, and mapping archaeological sites.

Side-Scan Sonar. For surveying large areas of the seabed, a transducer is either fixed to a vessel’s hull, or, to a “towfish” towed behind the vessel. The transducer emits fan-shaped pulses, and as for bathymetry, the echo is measured, recorded, and computed as …

2016年5月19日 · Side-scan Sonar is mainly used for the detection of objects and bottom structures. To obtain those images it digitises a sound pulse sent out from two transducers mounted on each side of the SSS fish.

Side-scan sonar Principle: Side-scan sonars emit conical or fan-shaped pulses across a wide angle perpendicular to the path of their towed sensors (‘towfish’). The received signals create a detailed image of the reflectivity of the sea floor (“sonograph”) and its anomalies within the swath (coverage width) of the beam.

Side Scan Sonar (SSS) is a widely used acoustic technique in the underwater archaeologist's toolkit. Within the AMZ cycle, SSS can be applied during the exploratory and mapping phases of a field survey to map objects on the waterbed.

2024年8月12日 · Side Scan Sonar. How It Works: Side scan sonar emits sound pulses to the sides, creating detailed images of the seafloor and underwater objects. Applications: Wreck detection, habitat mapping, and underwater archaeology. Limitations: Does not provide depth information directly. Example Models and Brands:

PURPOSE: Side-scan sonar (SSS) is an effective tool for inspecting the under-water portion of coastal structures. This note discusses SSS methods for in-specting both sloping and vertical-wall structures. used to map the sea bottom and search for submerged objects since the 1960's (Fleming, 1976).
