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 slant and/or range:
“The dead fed you
Amid the slant stones of graveyards.
Pale ghosts who planted you
Came in the night-time
And let their thin hair blow through your clustered stems.”
—Amy Lowell (1874–1925)
“Viewed freely, the English language is the accretion and growth of every dialect, race, and range of time, and is both the free and compacted composition of all.”
—Walt Whitman (1819–1892)
