Abstract
Apparatus for a beamrider missile guidance system in which a rotating rete wheel with a predetermined pattern of opaque and transparent segments is used to spatially encode a projected beam of electromagnetic radiation with the projected spatial information being used as a tone burst code with the frequency of the tone being proportional to missile position and the projected information being projected in two axes with appropriate timing of the burst for axis recognition.
