In radio electronics, especially [[radar]] terminology, '''slant range''' or '''slant distance''' is the distance along the [[relative direction (geometry)|relative direction]] between two points. If the two points are at the same [[level (coordinate)|level]] (relative to a specific [[Datum (geodesy)|datum]]), the slant distance equals the horizontal distance. 

An example of slant range is the distance to an aircraft flying at high altitude with respect to that of the radar [[antenna (electronics)|antenna]]. The slant range (1) is the hypotenuse of the triangle represented by the altitude of the aircraft and the distance between the radar antenna and the aircraft's [[Course (navigation)|ground track]] (point (3) on the earth directly below the aircraft). In the absence of altitude information, for example from a [[height finder]], the aircraft location would be plotted further (2) from the antenna than its actual ground track.
