👉 A sonar is a type of radar system used in maritime navigation, where it detects and measures sound waves from underwater objects to locate them. These sounds are reflected by the object and sent back to a receiver on land or at sea, which then converts the received sound into electrical signals that can be analyzed for information about the object's position and movement. Sonars have been instrumental in enabling ships and submarines to navigate through complex underwater environments without being entangled in debris or obstacles.
