SONAR, which stands for <\/span>Sound Navigation and Ranging<\/b>, is a powerful underwater detection system that uses sound waves to detect, locate, and identify objects beneath the water surface. It is widely used in <\/span>naval defense, submarine navigation, underwater exploration, fishing, and oceanographic research<\/b>.<\/span><\/p>\n

SONAR works on the principle of sound wave propagation in water, where sound travels much faster and farther than light, making it highly effective for underwater communication and detection.<\/span><\/p>\n

What is SONAR?<\/b><\/h2>\n

SONAR is a system that uses sound waves (usually ultrasonic waves) to detect objects under water and measure their distance, direction, and speed. It is mainly used where electromagnetic waves like radar cannot function effectively, especially in deep sea environments.<\/span><\/p>\n

Working Principle of SONAR<\/b><\/h2>\n

SONAR operates on a simple but powerful principle called echo or reflection of sound waves.<\/span><\/p>\n
