Sound Navigation and Ranging (SONAR)

Sound Navigation and Ranging (SONAR) is a technology that uses sound waves to detect and locate objects underwater. It works by sending out sound pulses and listening for their echoes as they bounce off objects like submarines or the ocean floor. By measuring the time it takes for the echoes to return, SONAR can determine the distance and shape of these objects. This system is widely used in marine exploration, navigation, and fishing, allowing submarines to move stealthily and helping researchers map the underwater environment.
