The electronic bearing line (EBL) on radar serves the function of providing a visual reference line on the radar display that indicates a specific bearing or direction relative to the radar antenna position. It allows radar operators to manually set or adjust a line on the radar screen corresponding to a desired rolling angle.
This feature aids in navigation and target tracking by providing a constant reference to monitor direction to a particular point of interest, such as another vessel, a navigation aid, or a designated waypoint.
EBL and VRM (variable range marker) are tools commonly found on radar displays. The EBL, as mentioned previously, represents a visual line indicating a specific bearing angle relative to the center of the radar. VRM, on the other hand, allows operators to mark a specific range distance from the radar position outward.
Together, these tools allow radar operators to quickly determine bearing and distance to targets or points of interest detected on the radar screen, improving situational awareness and assisting in navigation tasks.
The purpose of the Electronic Rolling Line (EBL) is to facilitate precise target tracking and navigation on radar systems. By allowing operators to set and adjust a line representing a specific bearing angle relative to the radar’s orientation, EBL helps visually reference the direction of targets or landmarks of interest.
This functionality is particularly useful for maintaining awareness of nearby vessels, navigating congested waterways, and conducting search and rescue operations, where accurate bearing information is essential for making informed decisions and maneuvering safely.
In the context of modern radar systems, EBL means electronic bearing line, which is a digital representation of a bearing line displayed on the radar screen. Unlike traditional mechanical bearing indicators, modern radar systems use electronic means to generate and display the EBL.
Operators can adjust the EBL electronically using controls on the radar interface, allowing quick and precise changes to the displayed roll angle. This digital capability improves the flexibility and usability of radar systems in various operational scenarios, ensuring effective target tracking and navigation capabilities
