🔍 Key Concepts

• Bearing vs range on marine radar (direction vs distance) • The meaning of resolution in radar (ability to separate two close targets) • How radar distinguishes targets that are close together in angle compared with distance

💭 Think About

• Ask yourself: when we talk about bearing, are we talking about the direction to a target or how far away it is? • Which answer choice focuses on separating targets that are close together in direction, not in distance, height, or size? • If two vessels are at the same range from you but slightly off to either side, what kind of resolution lets you see them as two separate echoes?

✅ Before You Answer

• Confirm that bearing refers to the direction (angle) from your vessel to the target. • Identify which option describes separation in direction while keeping distance the same. • Eliminate any choices that talk about distance, elevation, or size rather than direction/angle.
