An improved automatic missile tracking and guidance system wherein a laund missile is guided along a line-of-sight maintained by the operator with the target. The position of an infrared source disposed on the missile is detected and guidance signals generated in accordance therewith to control the flight of the missile along the line-of-sight. The infrared source or beacon disposed on the missile comprises an array of semiconductor light emitting diodes. The solid state characteristics of the light emitting diodes provide heretofore unobtainable reliability over existing beacons. The beacon may be used to produce a modulated, high frequency, rectangular waveform, incoherent emission offering performance improvements including virtual immunity to optical countermeasures.
