Marine Radar is a navigation and detection system used on ships and boats to identify other vessels, land, and obstacles in the water. It operates by emitting radio waves that bounce off objects and return to the radar system, allowing operators to determine the distance and direction of these objects. This technology is essential for safe navigation, especially in poor visibility conditions like fog or heavy rain. The information displayed on a marine radar screen helps sailors make informed decisions about their course and speed. It can also assist in collision avoidance and monitoring weather patterns, enhancing overall maritime safety.
