Marine radar works by emitting radio waves that reflect off objects, such as other vessels, land, or weather patterns, and return to the radar antenna. The system analyzes the time it takes for the signals to return, calculating the distance of objects based on their reflection. This data is displayed as a radar image, helping the navigator identify obstacles or other vessels in their vicinity. Marine radar systems operate at different frequencies, with higher frequencies providing better resolution but shorter range. Understanding how radar works is crucial for effective navigation.
