What is Sonar buoy?

A sonar buoy is a floating device used in underwater acoustics to detect and monitor underwater objects or phenomena, such as submarines or marine life. It employs sonar technology, emitting sound waves and analyzing their echoes to gather information about the underwater environment. Sonar buoys are often deployed from ships or aircraft and can operate autonomously or relay data back to a control center. They play a crucial role in naval operations, marine research, and environmental monitoring.
