A method is described analyzing the radiation characteristics of a spherical array by means of the Poisson sum technique. The elements are arranged as a series of circular arrays of different radii on a spherical surface. The main beam behaves as (sin u )/ u . A method of estimating other side‐lobe characteristics is also described; numerical examples are given.
