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 mountainous region of the State of Maine stretches from near the White Mountains, northeasterly one hundred and sixty miles, to the head of the Aroostook River, and is about sixty miles wide. The wild or unsettled portion is far more extensive. So that some hours only of travel in this direction will carry the curious to the verge of a primitive forest, more interesting, perhaps, on all accounts, than they would reach by going a thousand miles westward.”
—Henry David Thoreau (1817–1862)
“Panurge was of medium stature, neither too large, nor too small ... and subject by nature to a malady known at the time as “Money-deficiency,”Ma singular hardship; nevertheless, he had sixty-three ways of finding some for his needs, the most honorable and common of which was by a form of larceny practiced furtively.”
—François Rabelais (1494–1553)
