The knowledge of the independently optimum difference excitations, which provide the maximum normalized boresight slope, is exploited with an efficient excitation matching technique based on the contiguous partition method. A set of numerical experiments are provided to assess the effectiveness of the proposed method in reaching the best achievable performances even though with a small number of sub-arrays. 2008 IEEE.
