Abstract

This paper presents an optimal power pattern synthesis procedure able to tackle the mutual coupling and platform effiects even for electrically large arrays. The novelty of the approach is due to its capability to account in the synthesis procedure for two different aspects at the same time: the coupling between the array radiating elements and the coupling between these elements and the array platform. The mutual coupling evaluation is based on the active element pattern method, and the active element pattern is numerically computed. The kind of synthesis problems here addressed belongs to the class of convex optimization problems. Therefore, the solution is found by means of very efficient convex programming tools, without requiring global optimization schemes, thus saving time and costs. The extension of the overall tool to adaptive arrays is also considered.
