sonars
Submarine detection systems
Sonars is the plural of sonar, a technology that uses sound waves to detect objects underwater.
Ships and submarines use sonars to navigate, locate obstacles, and find other vessels: The submarine's sonars detected an approaching ship.
Marine researchers use sonars to map the ocean floor and track wildlife.
