Underwater sound imaging
Our company uses side-scan sonars, a category of sonars that emits fan-shaped beams towards the seafloor perpendicular to the sensor’s track, to obtain better images of underwater objects and features. The sensor can be towed by a boat or mounted on AUVs. The backscatter intensity is recorded for a very brief period of time, and by repeating the process as the device travels through the water, it provides a raw sonogram.
Based on the processed sonograms, it is possible to visualize, locate and measure the objects of interest found on the bottom of aquatic basins, the superficial features and structures of the sediments, and also to acoustically characterize and map the seafloor.
