Design of line source antennas for difference patterns with sidelobes of individually arbitrary heights

A design method previously developed to give a sum pattern with arbitrary sidelobe topography is shown to be applicable to difference patterns as well. The basis is Bayliss patterns (Taylor-type patterns for the difference mode) which are transformed through an iterative procedure to the desired result. For practical cases the convergence is rapid and a previously developed do-loop computer program has been modified to facilitate the computations and provide final patterns and aperture distributions.
