Abstract : The present invention is directed to a multi-beam optical processor type antenna controller for controlling an array antenna. In co-pending application Ser. No. 29,421, an optical processor antenna controller is disclosed. However, that antenna utilized only a single antenna pattern or beam. It is sometimes necessary or desirable to be able to control a multiplicity of patterns of beams which may be simultaneously or sequentially emitted from the antenna, and the present invention provides an apparatus for accomplishing this. The apparatus of the present invention utilizes a plurality of coherent light beams, each of which may selectively be shuttered out of the system if desired, for controlling the multiple antenna beams. It is thus an object of the invention to provide an optical processor apparatus for controlling a plurality of antenna beams. It is a further object of the invention to provide such an apparatus which is capable of independently inserting nulls into the pattern.
