A coherent optical processor antenna controller for controlling the pattern emitted by an array antenna. Since the amplitude and phase of the antenna excitation signals are related to the far field by the Fourier transform function, a coherent optical processor, which uses lenses to take the Fourier transforms of images may be used to control the antenna excitation. The shape and direction of the pattern may be controlled by the transmittance distribution of a transparency in the processor and a null may be formed by the utilization of an additional slide.
