What does sonar mean?
Sonar is short for the English word "Sound Navigation and Ranging", in Polish translation "Navigation and measurement with Sound". It is simply a technology utilized mainly in maritime navigation, but besides in another areas, specified as geological investigation or militaryry. In this article, I will tell you precisely what sonar is and how it works.
How does sonar work?
Sonar uses the rule of reflective sound waves from underwater objects. The sonar device sends an audible pulse that disperses in water and reflects from objects and is then received by the same system. Based on the time taken from sending the pulse to its reflection, sonar is able to find the distance to the object and its form and size.
Sonar Types
- Sonar active – sends sound pulse and receives reflection
- Passive Sonar – only receives sounds from underwater objects
Use of sonar
Sonar is widely utilized in various fields, mainly in marine navigation and underwater research. Below I present the most crucial areas where sonar is used:
1. Marine navigation
Sonar is an irreplaceable tool in maritime navigation, enabling detecting underwater obstacles specified as rocks or ship wrecks. Thanks to the sonar, captains can safely drive their units through hard aquenes.
2. Geological studies
Sonar is besides utilized to survey ocean bottom and geological structures underwater. With this technology, scientists can learn more about the chemical composition and geological composition of the seabed.
3. Military
In the field of military sonar is simply a key tool for detecting submarines and marine mines. Thanks to the sonar, the Navy can monitor marine waters and prevent threats.
Summary
Sonar is an advanced technology that plays a key function in marine navigation, geological investigation and military activity. Thanks to the usage of sound waves, sonar allows precise determination of the distance to underwater objects and their characteristics. I hope this article brought you closer to the subject of sonar and its applications.
