A Discussion of Taylor Weighting for Continuous Apertures

Abstract

It is shown that Taylor's beampattern for a continuous aperture can be computed analytically without Fourier transforming the weighting function itself, thereby achieving economies in computational effort in some modeling situations. A short Fortran program is given. An approximate formula for the half-power beamwidth is derived. It is pointed out that the Taylor weighting function can be negative for large n^_, a fact that does not seem to be well known. In addition, modification of Taylor's design to force the weighting function to go to zero as a power a of distance from the aperture endpoints is discussed. For a = 1 and a = 2 this results in an increase of 5% and 10% respectively, in the beamwidth.
