sonar detection
Underwater sound ranging
Sonar detection is the use of sound waves to locate objects underwater.
A sonar system emits pulses that bounce off submerged objects and return to a receiver, revealing their position and distance.
The technology is essential for submarines, ships, and marine research: The submarine used sonar detection to navigate through the channel.
Active sonar sends out signals; passive sonar listens for sounds made by other vessels.
