Side scan sonar

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. Our side scan sonar systems are respected as the standard of excellence in the industry and are deployed by governments, navies, port authorities, surveyors, oil companies and universities worldwide. Quick video illustrating the interpretation of side-scan sonar data collected with a recreational grade echosounder in a small pond. Side scan sonar creates a picture or an image of the sea floor. It measures the strength of how loud the return echo is, and paints a picture.

Hard areas of the sea floor like rocks reflect more sound and have a stonger or louder return signal than softer areas like sand. All side scan sonar systems are incapable of adequately imaging the region directly beneath the sonar tow body. Humminbird Side Imaging sonar uses a razor thin beam to take a “ sonar snapshot” of the area up to 4ft. The return image for this slice is then added to the images taken immediately before and after to build an incredibly detailed view of the lake bottom. I can then set a drift and rig the rods for how the fish are holding in that moment rather than blind-casting to a spot.

He also gives us a stellar explanation of how side-scanning sonar is working to produce those detailed pictures of the underwater world. Welcome to the future of seabed imaging! At DeepVision AB we are specialising in the development of high performance, low price sonar systems. You can now afford your own high performance side scan sonar system.

Sidescan Sonar (SSS) is a device that measures the intensity of the reflections from the seabed or objects on the seabed. SSS is usually towed approximately of the sonar operating range elevation above the seabed. A reliable sonar for general purpose surveys. Capture contacts and digitize features in real time or post processing. Preserve the full fidelity of sonar data across multiple formats.

For example SonarWiz allows for recording in industry standard XTF or vendor-specific formats such as Edgetech JSF or GeoAcostics GCF.

Finding fish with side imaging is difficult for most anglers since we don’t have enough screens on the boat.

We tend to select map, sonar and Down Imaging and forget about the side imaging, but finding fish is easy if you have the right conditions. However, like single-beam systems, they generate two main types of data, depth (or bathymetry) and backscatter. Traditionally, side scan sonars provide better backscatter data than depth data.

Like other sonars, a side scan transmits sound energy and analyzes the return signal (echo) that bounced off the seafloor or other objects. The sonar system ready to use. The method uses pulses of sound ( sonar ) shot sub-horizontally across the sea bottom from a towed transducer or towfish. In this application the instrument (towfish) is towed by a cable aft of the vessel.

Side-scan Sonar systems enable the acquisition of images of the seabed including any underwater structures such as wrecks, dam walls, dikes, pipelines etc. I found the course to be most informative for both beginners and professionals alike. Hull-mounted multibeam sonar (left) and towed side scan sonar (right). Side-scan sonar is a modern method of underwater imaging that can produce remarkably detailed and realistic views of shipwrecks and other bottom features using sound rather than light. It is a sonar that can look sideways.

Side -scanning sonar from brands such as Garmin, Humminbir Lowrance, Raymarine and Simrad scan abeam of the boat, exponentially multiplying bottom coverage and the chances of finding a new structure spot versus ­conventional down-looking sonar. Side - scan , or side -imaging, sonar has always intrigued me. Perhaps that’s because I’m a scuba diver, and I’ve experienced the underwater world in three dimensions.

Side-scan sonar systems enable emergency responders to cover a wide search area in a short amount of time, look for hazards before divers enter the water, and safely deploy divers after an object of interest is located. D Series side scan sonar can simultaneously transmit the CW or CHIRP signal. The echo signal was send to the deck unit by towfish through the underwater cable after receiving and processing, then processed by the sonar display-control software and generate the high resolution imaging data which can be saved to OTSS and XTF formats used to replay. The use of side scan sonar to search for drowning victims and other underwater objects.

Side-scan sonar is an effective tool for identifying seabed objects or items of debris as it creates an image of the sea floor, using sound energy and strength of signal return to cover large areas quickly and cost-effectively.

In contrast to single-beam sonar , which bounces a single focused beam of sound off the bottom to measure depth, side scan sonar casts a broader, fan-like signal, creating nuanced readings of the contour of the ocean floor and yielding photo-like images.

SIDE SCAN SONAR WHAT IS IT? Sonar (SOun NAvigation and Ranging) is a technique that uses sound waves to detect and locate. Many people have written in with questions about the side-scan sonar image, so I’ve put together a quick description of the sonar screen and how to interpret it.
