Abstract
Abstract Missile guidance system utilizing laser beams. A beam is directed from a suitable source onto the missile and reflected by appropriate reflective means thereon directly back toward the source at which point it is received into a suitable optical system and caused to fall upon a position sensitive detector. Displacement of the beam on said detector from a predetermined zero point is appropriately interpreted and signals resultant therefrom are applied to a further laser generator. The modulation of said signals appears in the beam generated by said last-named generator, is directed in a sufficiently wide cone to cause it to fall upon the missile, is received therein and applied to a detector. Said detector appropriately interprets such beam and effects the necessary correction of the missile course to return it to the desired flight path. Appropriate filters are applied to the optical receiving means in both the control station and the missile to filter out stray light and insure both thereof being sensitive only to the desired laser beam.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
148 words
A missile guidance system, comprising: a transmitting station having means defining a laser adapted to transmit a guidance electromagnetic radiation signal to a zone spaced from said transmitting station; means comprising a missile and propulsion means for propelling said missile to and into said zone, said missile means including guidance signal receiving means responsive to said guidance signal for controlling the movement of said missile while in said zone; means comprising a source of a location electromagnetic radiation signal on said missile means which is adapted to transmit same rearwardly thereof; a receiving station located adjacent said transmitting station and having means defining a location electromagnetic radiation signal receiver for said location electromagnetic radiation signal from said missile, said location electromagnetic radiation signal receiver means including means for locating said missile means in said zone and producing said guidance signal in response to said location electromagnetic radiation signal.
Claim 2
Dependent Claim
148 words
A missile guidance system, comprising: a transmitting station having means defining a laser adapted to transmit a guidance electromagnetic radiation signal to a zone spaced from said transmitting station; means comprising a missile and propulsion means for propelling said missile to and into said zone, said missile means including guidance signal receiving means responsive to said guidance signal for controlling the movement of said missile while in said zone; means comprising a source of a location electromagnetic radiation signal on said missile means which is adapted to transmit same rearwardly thereof; a receiving station located adjacent said transmitting station and having means defining a location electromagnetic radiation signal receiver for said location electromagnetic radiation signal from said missile, said location electromagnetic radiation signal receiver means including means for locating said missile means in said zone and producing said guidance signal in response to said location electromagnetic radiation signal.
Claim 3
Dependent Claim
31 words
A missile guidance system according to claim 1, wherein said transmitting station includes modulation means for modulating said guidance signal on said electromagnetic radiation from said laser in said transmitting station.
Claim 4
Dependent Claim
138 words
A missile guidance system according to claim 2, wherein said transmitting and receiving stations combined include means defining a sight optic device for defining a theoretical line of sight into said zone illuminated by electromagnetic radiation from said laser at said transmitting station, calculator means responsive to said location signal for determining the angle between said line of sight and location of said missile means, said calculator means being adapted to produce said guidance signal proportional to said angle determination and signal connection means for connecting said modulation means to said calculator means, said modulation means being responsive to said guidance signal from said calculator means to modulate said guidance signal on said electromagnetic radiation from said laser in said transmitting station to effect a control of said missile means to move same toward said line of sight.
Claim 5
Dependent Claim
51 words
A missile guidance system according to claim 1, wherein said source means of a location electromagnetic radiation signal on said missile is defined by a mirror mounted on the aft end of said missile means which is adapted to reflect electromagnetic radiation from said transmitting station rearwardly of said missile means.
Claim 6
Dependent Claim
22 words
A missile guidance system according to claim 1, wherein said location electromagnetic radiation signal receiver means includes a position sensitive detector means.
Claim 7
Dependent Claim
39 words
A missile guidance system according to claim 1, wherein said guidance signal receiving means includes interpreting means for interpreting said guidance signal and effecting a control of said propulsion means and the direction of flight of said missile means.
