Analytic techniques for the design of non-regular arrays

Analytic techniques to the design of linear and planar thinned arrays with predictable and well-behaved sidelobes are presented in this paper. The element placement is based on almost difference sets and the array power pattern is forced to pass through a set of uniformly-spaced samples which are a-priori known. Such a property allows one to predict the peak sidelobe. Numerical examples are reported for both linear and planar array arrangements.
