Abstract
A grid-search type placement method for the assembling of large, non-uniform, linear arrays is presented. The required data is generated by means of an efficient computational engine that provides the locations of the elementary radiators for user-specified beam-widths and peak side-lobe levels. The scanning properties of the designed arrays are also investigated. An effective method for reducing the side-lobe level at large scanning angles is contrived.
