A guidance system for a beam rider missile, having a novel coded light beam projector at an aiming station, for use by a missile-mounted receiver. The projecting means contains a rotating transparent reticle through which the beam is transmitted, the reticle having an opaque radial portion in a curved 'leaf' shape. When the diameter of the projected beam is held constant at the missile distance during flight, the position of the missile in polar coordinate form is given by the relative angular position and duration of the blocked-out portion of the beam received at the missile.
