%T Synthesis of Sub-Arrayed Monopulse Planar Arrays by Means of an Innovative Excitation Matching Method
%X Planar antenna arrays are widely used as transmitting and receiving part of monopulse trackers because of the need to generate sum and difference radiation modes to estimate the angular location of an unknown target. In such a framework, this paper presents an innovative synthesis technique able to synthesize two orthogonal sub-arrayed difference patterns close to an optimal reference one. The proposed numerical results assess the effectiveness of the proposed approach also dealing with large arrays.
