Van Atta array is used to receive a millimeter wave beam from a beam transmitter located in a missile in flight and retransmit the beam back to its source along its original optical path after the beam is phase conjugated and modulated at a tracking station by imparting to it missile guidance information. The missile extracts guidance information from the retransmitted beam and guides its trajectory closer to the course leading to the target.

A method for guiding a missile toward a target while the missile is in flight, comprising the steps of: visually tracking a target from a target tracking station, issuing a millimeter wave beam from the missile in flight toward the tracking station, receiving the millimeter wave beam at the tracking

A method for guiding a missile toward a target while the missile is in flight, comprising the steps of: visually tracking a target from a target tracking station, issuing a millimeter wave beam from the missile in flight toward the tracking station, receiving the millimeter wave beam at the tracking station, performing amplification on the received beam at the tracking station, performing phase conjugation on the received beam at the tracking station, modulating the phase-conjugated amplified beam to impregnate said beam with angular offset of said beam from the line-of-sight of the target, redirecting the modulated beam along its original optical path back to the missile, receiving the redirected beam by the missile, and generating guidance signals in the missile in response to the received redirected beam to guide the missile in the direction to reduce said angular offset.
