azimuth resolution
The ability of radar equipment to separate two reflectors at similar ranges but different bearings from a reference point.
In the first figure, the distant objects subtend a very small angle and they appear as one big blip or target on radar screen. In the second figure, however, the two aircraft are far enough apart in azimuth to be seen as two spots on the screen.
Targets a, b can be discriminated by narrower beam, whereas targets c and d tend to merge and appear as one target.
Normally, the minimum separation distance between the reflectors is quoted and expressed as the angle subtended by the reflectors at the reference point.
