  • 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
