Side-scan uses a sonar device that emits conical or fan-shaped pulses down toward the seafloor across a wide angle perpendicular to the path of the sensor through the water, which may be towed from a …

Jun 22, 2020 · 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 …

From six to six thousand meters, EdgeTech Side Scan Sonars offers advanced sonar imaging, search and recovery, survey and UED detection systems and solutions. Review All EdgeTech Sonar Products.

Mar 27, 2026 · Side scan sonar (SSS) is an underwater acoustic imaging system used to map the seabed and detect underwater objects. It produces high-resolution imagery by emitting sound waves …

Side-scan sonar (SSS) is defined as a sonar system that efficiently creates images of large areas of the seafloor, used for mapping, detecting underwater objects, and identifying bathymetric features.

To map the seafloor, scientists tow a sidescan sonar 500 meters above the bottom. It sends sound waves that reflected off surfaces, revealing texture and hardness.

Feb 6, 2026 · Side scan sonar is a form of active sonar designed to image the seafloor and detect underwater objects by emitting sound waves at angles perpendicular to a transducer-equipped …

Side-scan sonar imaging is a swath-mapping technique based on acoustic backscatter properties of the seafloor. A descendant of wide- beam echo sounders, a side- scan sonar system comprises arrays …

Side Scan Sonar (SSS) is an established technology used to generate detailed acoustic images of the seafloor. This method employs sound waves instead of light to survey large underwater areas …

Basic features: Side-scan sonars are very useful for mapping archaeological features that are visible on or above the bottom (wrecks, exposed pole and rock structures, etc.)
