An ___________ measures the radar bearing of an object on the radar screen.

An Electronic Bearing Line (EBL) is a feature used in radar systems to assist navigators in determining the bearing of an object displayed on the radar screen. It allows the operator to draw a line from the center of the radar display to a specific target, indicating the angle or direction to that target relative to the vessel's heading. This capability is essential for various navigational tasks, such as collision avoidance and plotting a course toward a waypoint or other maritime object. By accurately identifying the radar bearing of an object, navigators can make informed decisions and maintain situational awareness while at sea.
