đ 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
đ 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?
â
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.
