Pattern Synthesis of Sub-Arrayed Monopulse Planar Arrays

Abstract

Synthesis of sum and difference patterns of a planar array is introduced in this article by means of a clustering algorithm. The whole array aperture is divided into several sub-arrays, which will reduce the cost and complexity of manufacturing the array antenna. The sub-array configurations and the corresponding sub-array weights are defined to minimize the maximum level of the side-lobes of the corresponding sum and difference patterns. Two kinds of arrays are considered here: in the first, the whole aperture is divided into several sub-arrays to get sum and difference patterns; in the other, the compromise difference pattern is obtained. Some numerical experiments are given to assess the feasibility and effectiveness of the proposed method.
