Side Scan Sonar Survey Definition

Side scan sonar systems consist of a dual channel tow fish capable of operating in the water depths for the survey and contain a tracking system.

Side scan sonar survey definition.

The full body three fin hydrodynamic. Summary the global side scan sonars market will reach volume million usd in 2018 with cagr xx 2018 2025. Side scan sonar is a category of active sonar system for detecting and imaging objects on the seafloor. The equipment is use to obtain complete coverage of the specified areas and operates at scales commensurate with line spacing optimum resolution and 100 data overlap.

Side scan sonar uses acoustic signals sound waves to generate an image of the seafloor riverbed lakebed etc. Side scan sonar may be used to conduct surveys for marine archaeology. Side scan sonar systems consist of a dual channel tow fish capable of operating in the water depths for the survey and contain a tracking system. Like other sonar systems multibeam systems emit sound waves in a fan shape beneath a ship s hull.

The starfish range has gained worldwide recognition as the most compact affordable towed side scan sonars for the professional underwater survey industry. The amount of time it takes for the sound waves to bounce off the seabed and return to a receiver is used to determine water depth. In conjunction with seafloor samples it is able to provide an understanding of the differences in material and texture type of the seabed side scan sonar imagery is also a commonly used tool to detect debris items and other obstructions on the seafloor that may be hazardous to shipping or to seafloor installations by. High resolution side scan sonar shallow water.

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. The main contents of the report including. A side scan sonar is often towed behind a survey vessel but may be affixed directly to the vessel for shallow water applications. Multibeam sonar systems provide fan shaped coverage of the seafloor similar to side scan sonar but with different data output.

Where side scan sonar continuously records the strength of the return echo ping multibeam systems measure and record the time for the acoustic signal to travel from the transducer to the seafloor and back. A multibeam echosounder is a type of sonar that is used to map the seabed.
