An application of Kern's 'transmission integral' to defocusing errors in offset-fed parabolic reflector antennas
Abstract
Kern's (1981) transmission integral is used to calculate defocusing errors on offset-fed parabolic reflector antennas. This approach yields the scattering matrix for the parabolic reflector and is therefore applicable to any type of feed. Sample calculations of the two-dimensional fast Fourier transfer are given for a parabola with a focal-length-to-diameter ratio of 0.4.
