摘要

A common method of antenna array synthesis uses least-squares approximation to fit the radiation pattern of the array to a set of samples of an ideal desired pattern F(id). However, it has long been known that discontinuities in F(id) prevent close approximation, and that sampling a target pattern F(tar) that approximates F(id) can afford better results. Here we show, for the case of circular planar arrays, that an appropriate target pattern can be obtained by modification of a Taylor pattern for a circular aperture.
