Question 8-38D4
Element 8 (RADAR)Bearing resolution is:
Explanation
Bearing resolution, also known as angular resolution, is the ability of a receiver system (often with a directional antenna) to differentiate between two distinct signal sources or "targets" that are very close to each other in direction. If two targets are at the same distance but coming from slightly different angles (bearings), a system with good bearing resolution can identify them as separate.
Option A correctly defines this concept by specifying "adjacent targets" (close in angle) and "equal distance" (to isolate the angular aspect from range).
Option B describes *range resolution*, the ability to distinguish targets at different distances.
Option C describes *elevation resolution*, the ability to distinguish targets at different vertical angles.
Option D relates to target characteristics like radar cross-section or signal strength, not a form of positional resolution.
