A beamrider guidance system for missiles wherein a laser beam is given two circular motions around the boresight axis to produce amplitude and phase modulation on the signal received at the missile. The information on distance from boresight is contained in the amplitude modulation and the angular information is contained as phase modulation. A laser optical system with a spinning holographic element provides one of the circular motions for the beam. The other circular motion is provided by a low frequency, circular scanning mirror.

In a beamrider missile guidance system wherein a target is tracked by line-of-sight from a tracking station and a missile is directed toward the target substantially along the line-of-sight axis, a method of directing the missile toward the target and comprising the steps of: visually tracking a target from a target tracking station, directing a laser beam of optical energy from said target tracking station toward said target and along a path offset a constantly varying distance from said line-of-sight; directing a missile toward said target within the path of said optical energy beam; and generating correctional guidance within the missile in response to the position of said missile away from the line-of-sight and within said beam.
