Vertical side-lobe suppression in cylindrical arrays

Abstract

The vertical side-lobe structure of cylindrical arrays driven in phase is examined. Experimental results demonstrate that the vertical side-lobe levels are significant when the angular aperture of the array is large.The physical cause of this phenomenon is identified, and a method of eliminating excessi•,e side-lobe levels is explained. Experimental results showing that this method is successful are presented. PACS numbers: 43.30 Yj, 43.30 Vh.
