What role does radar play in electronic navigation?

Radar plays a critical role in electronic navigation primarily through its ability to detect and track other vessels and obstacles in the navigational environment. By using radio waves, radar systems can identify the presence and movement of objects, allowing navigators to gauge their relative positions and avoid potential collisions. This functionality is essential for maintaining situational awareness, especially in crowded or low-visibility conditions such as fog, rain, or nighttime.

The ability to track moving vessels enables mariners to make informed decisions about course changes, speed adjustments, and navigation safely through busy waterways. Radar systems can also provide information regarding the distance and bearing of detected objects, which helps in planning maneuvers and ensuring navigational safety. Additionally, modern radar technology often integrates with other electronic navigation systems to enhance overall navigation efficiency.
