Sonar

What is the definition of sonar?

Stands for sonic navigation and ranging. Sonar uses acoustic (sound) waves to detect and measure the distance to objects or surfaces through soundwave reflection (echoing) and detection.

Sonar uses a high-accuracy timing device to measure how long it takes from the time that the emitted sound to travel both to and from the object or surface. Using this duration and the speed of the sound, the range can be accurately calculated.
