Which term denotes the ability to distinguish two targets that are close in azimuth at the same range?

• A. Azimuth resolution
• B. Elevation resolution
• C. Range resolution
• D. Scintillation

Answer: (A)

Azimuth resolution describes the ability to distinguish two targets that are close in azimuth at the same range. It measures how finely a sensor can separate objects in the horizontal angle plane; a narrower beam or larger aperture yields better azimuth resolution. Practically, if two targets share the same distance but sit at slightly different angles, good azimuth resolution lets you see them as two distinct targets rather than a single blur. Elevation resolution would deal with vertical separation, range resolution with distance along the line of sight, and scintillation refers to signal fluctuations caused by the environment rather than the ability to separate targets.
