SONAR is a technology that has extensive marine application by sending and receiving ultrasound that bounces off objects at sea. And in this article, i’ll be discussing what it actually is.
With that said, let’s delve in and take a look at what the concept really entails – Here’ everything you need to know about SONAR.
SONAR is an acronym, meaning Sound Navigation and Ranging. It’s a type of technology that uses sound waves to navigate, explore, map, communicate with or detect objects under or on the surface of water.
Also, it’s the machine that produces and receive the sound waves – echoes. It’s very useful because sound waves travel faster in water than RADAR and light waves.
And there’re two types of sonar – active sonar and passive sonar. Simply put, the formal is emitting pulses of sound waves (or an acoustic signal) and the latter is listening to emitted sound waves.
Uses of Sonar.
- It’s used to search for and map objects on the seafloor
- Used to locate underwater hazard to navigation
- Used to develop nautical charts by NOAA (National Ocean and Atmospheric Administration) scientists.
- It’s also used to map the seafloor itself.
