Full Form of SONAR
SONAR stands for Sound Navigation and Ranging. It is a technology that uses sound propagation to navigate, communicate with, or detect objects on or under the surface of the water.
Key Components of SONAR:
Sound Waves: SONAR operates by emitting sound waves and analyzing the echoes that return after bouncing off objects.
Navigation: It helps in determining the distance to objects and navigating through water.
Ranging: SONAR can measure the depth of water bodies and the distance to the seabed or underwater features.
Types of SONAR:
- Active SONAR:
- Emits sound pulses and listens for echoes.
Used for detecting submarines, schools of fish, or underwater obstacles.
Passive SONAR:
- Listens for sounds made by other vessels or marine life.
- Used primarily for surveillance and reconnaissance.
Applications of SONAR:
- Marine Navigation: Used by ships and submarines to navigate safely.
- Fisheries: Helps in locating schools of fish.
- Oceanography: Assists in mapping the seafloor.
- Military: Used for submarine detection and tracking.
In summary, SONAR is an essential technology in various fields, providing valuable information for navigation, exploration, and research in aquatic environments.
