In harbor safety and security, sonar (Sound Navigation and Ranging) is essential for underwater surveillance, detection, and navigation. It operates by emitting sound waves that detect objects beneath the water's surface, making it invaluable for identifying submerged obstacles, mapping the seafloor, and ensuring safe passage for vessels. Sonar systems help in locating potential security threats, such as unauthorized divers or underwater drones, enhancing port defense measures. It also aids in inspecting and maintaining underwater infrastructure like piers and docks, supporting regular maintenance and reducing the risk of structural failure. Overall, sonar is a powerful tool for underwater situational awareness in harbor environments.
