Sonar, short for Sound Navigation and Ranging, is a technique that uses propagation of sound waves to communicate, navigate and detect the objects on or under the surface of the water.
Working of sonar:
- Sonar can send the sound waves towards the depth of the ocean
- When these sound waves hit the objects like fish, vegetation or the bottom of the ocean , they are reflected back to the surface in the form of echo.
- The sonar device measures how long it takes for the sound wave to travel down, hit an object and then bounce back up.
- This information enables the device to to measure the depth of the object
- And also it measures the strength of the returning pulse to know the the strength of the objects. The harder the objects, the stronger the return of the sound wave.
