Abstract
A method for wide null-steering in the pattern of a uniformly excited linear array that utilizes the edge elements of the array is investigated. Simpler and faster algorithms for sidelobe reduction are introduced which use one or two external edge elements. Comparisons between these methods are held. Sample results are given
