To “see” in the water, sonar uses sound waves. When using an imaging sonar, it is more beneficial to spend some time with the vehicle sat on the bottom while the sonar scans the area around it rather than traveling.
The operating frequency, the acoustic beam width, the processing power, and the amount of time it takes to form an image all play a role in how well an imaging sonar performs, from the distance at which it can detect an object to the clarity of the image and the number of images it can display per second. Sound Metrics sonars make use of zero-power acoustic lens technology to instantly form beams.
In general, an image can be captured at a greater distance at a lower frequency. Images will be clearer when used to map an object with a frequency that is higher and a beamwidth that is smaller. The clarity with which an imaging sonar can capture a target is unaffected by the deployment depth.
Sonar is mostly used by NOAA scientists to make nautical charts, find underwater hazards to navigation, find shipwrecks on the seafloor and map them, and map the seafloor itself.
Similar to a medical ultrasound sonogram, Sound Metrics imaging sonars transmit sound pulses and transform the echoes that return into digital images. They can “see” what’s going on through dark or turbid (cloudy) water in conditions of zero visibility, which is a benefit.
The Global Sonar Imaging Devices market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
At this year’s Oceanology International conference and exhibition in London, Tritech International Limited announced the Micron Gemini’s release. The newest member of the Micron and Gemini product families is the smallest multibeam sonar currently available. Housed inside the Gemini, it is a powerful real-time imaging sonar that is extremely affordable.
Utilizing Tritech’s Diver Mounted Display (DMD) and offering cost-effective obstacle avoidance and navigation for small ROVs and AUVs, the Micron Gemini has significantly improved image quality.
