Sonar (Sound Navigation and Ranging) is a technology that uses sound waves to detect objects underwater. Sonar systems consist of a transmitter, which emits sound waves, and a receiver, which detects the sound waves that bounce back after hitting an object.
When the sound waves hit an object, they bounce back to the receiver, which detects the echo and measures the time it took for the sound wave to travel to the object and back. Based on the time taken, the distance to the object can be calculated using the speed of sound in water.
The sonar system can also determine the direction and speed of the object by analyzing the changes in the frequency and amplitude of the sound waves as they bounce back from the object.
Sonar is used in a variety of applications, including navigation, oceanography, fishing, and military operations. It is an essential tool for underwater exploration and provides valuable information about the underwater environment.
