Synthetic Aperture Sonar (SAS)
Synthetic Aperture Sonar (SAS) is an advanced underwater imaging technology used to create high-resolution images of the seabed. It works by moving a sonar device, often mounted on a boat or underwater vehicle, across a body of water. As it moves, it sends out sound waves that bounce off the seabed and return to the device. By processing these echoes and combining data collected from multiple positions, SAS can produce detailed images, allowing for better mapping of underwater landscapes, detecting objects, and conducting surveys, all vital for marine research and exploration.

Synthetic Aperture Sonar (SAS) is an advanced imaging technology used underwater, similar to radar but for sonar. It helps create high-resolution images of the seafloor and underwater objects. SAS works by moving a sonar device, often mounted on a boat or submersible, while it sends out sound waves. These sound waves bounce off objects and return to the device. By processing the data collected over a larger area, SAS synthesizes a virtual ‘aperture’ that enhances image clarity, allowing for detailed mapping and exploration of marine environments, which is valuable for industries like fishing, archaeology, and environmental monitoring.
