Early Warning Radar

An early warning radar is any radar system used primarily for the long-range detection of its targets, i.e., allowing defences to be alerted as early as possible before the intruder reaches its target, giving the defences the maximum time in which to operate. This contrasts it with systems used primarily for tracking or gun laying, which tend to be shorter range but offer much higher accuracy.

Famous quotes containing the words early, warning and/or radar:

    When lilacs last in the dooryard bloomed
    And the great star early drooped in the western sky in the night,
    I mourned, and yet shall mourn with ever-returning spring.
    Ever-returning spring, trinity sure to me you bring,
    Lilac blooming perennial and drooping star in the west,
    And thought of him I love.
    Walt Whitman (1819–1892)

    An overturned cart is a warning to oncoming drivers.
    Chinese proverb.

    So I begin to understand why my mother’s radar is so sensitive to criticism. She still treads the well-worn ruts of her youth, when her impression of mother was of a woman hard to please, frequently negative, and rarely satisfied with anyone—least of all herself.
    Melinda M. Marshall (20th century)
