sonar imaging
Sound-based underwater visualization
Sonar imaging uses sound waves to create visual representations of underwater environments or objects.
A device emits pulses of sound that bounce off surfaces and return; the timing and strength of these echoes are processed to generate images of the seafloor, submerged structures, or marine life.
The technology is essential for naval operations, fishing, marine archaeology, and oceanographic research.
Sonar imaging revealed the shipwreck lying three hundred meters below the surface.
