Sonar (Sound Navigation and Ranging) is an acoustic counterpart to radar, utilizing sound waves rather than electromagnetic waves to detect objects. Primarily used underwater, sonar systems are vital for submarine navigation, fish finding, and underwater mapping. While radar can penetrate the air, sonar excels in detecting underwater targets, such as submarines or shipwrecks. Active sonar sends sound waves, and passive sonar listens for sounds. The key difference between sonar and radar is that sonar is used in aquatic environments, while radar is typically used in air or land-based applications.
