A digital computer was used as a mechanical observer to evaluate antenna image quality as a function of the aperture illumination for a high resolution antenna. An illumination close to uniform was found to yield an image that was best as measured by the ease with which the mechanical observer was able to analyze the images. A description of the logical design of the observer and the results of applying it to the analysis of a typical class of illuminations are given.
