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 […]
