Abstract The pattern of a circular aperture with errors normally requires a double numerical integration. When the aperture function is rotationally symmetric or with sin θ variation, the double integration can be reduced to a single integration of a Struve function; these are readily calculable. Thus the pattern calculation is greatly simplified. © 1995 John Wiley & Sons, Inc.
