Sonar technology is a system that uses sound propagation to navigate, communicate, or detect objects underwater. It stands for Sound Navigation and Ranging. Sonar technology is commonly used for mapping the ocean floor, detecting underwater objects, measuring water depth, and communication underwater. Sonar systems emit sound waves that bounce off objects in the water, and the returning signals are analyzed to provide information about the object's location, size, and shape. Sonar technology is vital for military operations, marine navigation, underwater research, and fishing industries. Advancements in sonar technology have led to the development of more precise and efficient underwater imaging and detection systems.
