Title :
Low sidelobe taper choice for wideband adaptive arrays

Abstract :
Chebychev and Taylor weightings are both used to produce low sidelobe patterns for array antennas. The Chebychev taper may be considered superior because it produces a narrower mainlobe for a given maximum sidelobe level. However, for wideband adaptive arrays the Taylor apodization can result in narrower interference nulls, thus providing better overall adaptive beamformer performance.
