Direction finding (DF) refers to the establishment of the direction from which a received signal was transmitted. This can refer to radio or other forms of wireless communication. By combining the direction information from two or more suitably spaced receivers (or a single mobile receiver), the source of a transmission may be located in space via triangulation.

Famous quotes containing the words direction and/or finding:
“The young ... look into visages dull-eyed, long-toothed, wattle-necked, and chop-fallen, something they have never been and which they cannot imagine ever being.... If it occurs to a young person, looking at us, that this is the direction in which he himself travels, how can he forgive, let alone bear the sight of, us, who constantly bring him the bad news of our own faces, bitter signposts pointing to his own destination?”
—Jessamyn West (1902–1984)
“If everybody is looking for it, then nobody is finding it. If we were cultured, we would not be conscious of lacking culture. We would regard it as something natural and would not make so much fuss about it. And if we knew the real value of this word we would be cultured enough not to give it so much importance.”
—Pablo Picasso (1881–1973)
