Sonar, technique for detecting and determining the distance and direction of underwater objects by acoustic means. Sound waves emitted by or reflected from the object are detected by sonar apparatus and analyzed for the information they contain.
Sonar (sound navigation and ranging or sonic navigation and ranging) [2] is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels.

Sonar, which stands for Sound Navigation and Ranging, is a technology that has revolutionized how we explore and interact with the underwater world. It is used in a wide range of applications, from detecting submarines and mapping the ocean floor to locating schools of fish or even navigating through the water.
Sonar, short for Sound Navigation and Ranging, is helpful for exploring and mapping the ocean because sound waves travel farther in the water than do radar and light waves. NOAA scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and map objects on the sea floor such as shipwrecks, and ...
The meaning of SONAR is a method or device for detecting and locating objects especially underwater by means of sound waves sent out to be reflected by the objects; also : a device for detecting the presence of a vessel (such as a submarine) by the sound it emits in water.
Sonar, which is short for “Sound Navigation and Ranging” is used to help both explore and map the ocean. It is especially useful in ocean exploration because sound waves have the ability to travel more efficiently through the water (and farther) as opposed to light or radar waves, which have also been used in the past to help explore the ocean.
SONAR, short for SOund NAvigation and Ranging, is a tool that uses sound waves to explore the ocean. Scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and identify objects in the water column and on the seafloor such as shipwrecks, and map the seafloor itself.
Sonar definition: a method for detecting and locating objects submerged in water by echolocation.. See examples of SONAR used in a sentence.
SONAR definition: 1. equipment, especially on a ship, that uses sound waves to discover how deep the water is or the…. Learn more.
In simple terms, sonar is a technique that uses sound waves to detect and locate objects in the water. The basic principle behind sonar technology is that it sends out a sound signal, which travels through the water and bounces off any object in its path.
