• beam width — The full angular interval in the horizontal plane between the points at which the power radiated from the antenna has fallen to half its maximum value. In practice, the effective beam width may be less than this value and may be altered by use of …   Aviation dictionary

• beam resolution — The ability of a radar to distinguish between two targets that are at the same range but different azimuths. Radar resolution in azimuth is a function of beam width. The narrower the beam, the better the resolution …   Aviation dictionary

• 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… …   Aviation dictionary

• fan beam — A fan shaped radar beam, broad in the vertical plane and narrow in the horizontal plane. A fan beam allows only the measurement of the azimuth angle. Typically, a fan beam in aircraft surveillance radar is 1° to 2° in azimuth and 20° to 40°, or… …   Aviation dictionary

• Pencil beam — A pencil beam is a beam of radiant energy in the form of a narrow cone or cylinder.Antennas which strongly bundle in azimuth and elevation are often described as a pencil beam antenna. For example the phased array antenna can send out a beam thin …   Wikipedia
