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

Abstract

A design method is presented for the determination of continuous line sources which will yield sum patterns consisting of a narrow main beam and sidelobes whose individual heights can be adjusted to any arbitrary specification. The method is based on a generalized Taylor pattern which is perturbed in successive iterations until the desired pattern results. For practical cases the convergence is rapid, and an economical computer program of general applicability has been written which will terminate when the desired pattern has been achieved within a specified tolerance, at which point a final pattern and aperture distribution are printed out. The theory is illustrated by several cases of practical interest.
