Guidance
See also: Missile guidanceGuided missiles operate by detecting their target (usually by either radar or infrared methods, although rarely others such as laser guidance or optical tracking), and then “homing” in on the target on a collision course.
Although the missile may use radar or infra-red guidance to home on the target, the launching aircraft may detect and track the target before launch by other means. Infra-red guided missiles can be “slaved” to an attack radar in order to find the target and radar-guided missiles can be launched at targets detected visually or via an infra-red search and track (IRST) system, although they may require the attack radar to illuminate the target during part or all of the missile interception itself.

Famous quotes containing the word guidance:
“The rest, called literature, is a dossier of human imbecility for the guidance of future professors.”
—Tristan Tzara (1896–1963)
“Children require guidance and sympathy far more than instruction.”
—Anne Sullivan, U.S. educator of the deaf and blind. The Last Word, ed. Carolyn Warner, ch. 16 (1992)
“Even healthy families need outside sources of moral guidance to keep those tensions from imploding—and this means, among other things, a public philosophy of gender equality and concern for child welfare. When instead the larger culture aggrandizes wife beaters, degrades women or nods approvingly at child slappers, the family gets a little more dangerous for everyone, and so, inevitably, does the larger world.”
—Barbara Ehrenreich (20th century)
