Abstract
In accordance with this invention, a missile referenced beamrider guidance ink is provided in which a continuous wave or pulsed laser output is formed into a gaussian cross section or similarly shaped beam and projected to one offset sensor, or to two sensors located on opposite sides and as far from the missile's roll axis as possible. The rolling missile motion amplitude modulates the received signal and the amplitude of the modulation is a measure of the missile's distance from beam axis. The phase of the modulation provides the direction to beam center.
