acoustic sonar

Acoustic sonar is a technology that uses sound waves to detect and locate objects underwater. It works by emitting sound pulses, which travel through water and bounce back when they hit an object or the seabed. The sonar system then measures the time it takes for the echoes to return, helping determine the distance and position of underwater features. This technique is widely used for navigation, mapping the ocean floor, detecting schools of fish, and underwater exploration. Because sound travels efficiently in water, sonar provides a reliable way to see and understand the underwater environment where light-based sensing is limited.
