Slant Range

In radio electronics, especially radar terminology, slant range is the line-of-sight distance between two points which are not at the same level relative to a specific datum.

An example of slant range is the distance to an aircraft flying at high altitude with respect to that of the radar 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 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 farther (2) from the antenna than its actual ground track.

Famous quotes containing the words range and/or slant:

    In the range of things toddlers have to learn and endlessly review—why you can’t put bottles with certain labels in your mouth, why you have to sit on the potty, why you can’t take whatever you want in the store, why you don’t hit your friends—by the time we got to why you can’t drop your peas, well, I was dropping a few myself.
    Mary Kay Blakely (20th century)

    There’s a certain Slant of light,
    Winter Afternoons—
    That oppresses, like the Heft
    Of Cathedral Tunes—
    Emily Dickinson (1830–1886)
