Radar range refers to the maximum distance a radar system can detect an object. The range is influenced by factors such as the power of the radar signal, the frequency used, and environmental conditions like weather or sea state. Higher-powered radar systems can detect objects at greater distances, while lower-powered systems may offer better resolution but with a shorter range. Radar range is crucial for safe navigation, particularly in open waters or during low-visibility conditions like fog, ensuring that a vessel can detect obstacles or other vessels at a sufficient distance to avoid collisions.
