Abstract : A coherent optical processor antenna controller which is capable of inserting deep nulls in the antenna pattern at selected locations, without degrading the remainder of the pattern. The processor includes a means for optically forming the far field antenna pattern at a plane and a means for sampling the far field pattern with a matrix of apertures at positions corresponding to the desired positions of the nulls being blocked.
