An innovative approach for the optimization of a set of user-defined features of sub-arrayed difference beams has been presented. The obtained results assess the effectiveness as well as the reliability of the proposed approach. Moreover, thanks to the exploitation of some properties of the solutions of the problem and the efficiency of the searching procedure, the proposed method demonstrated a significant saving of computational costs. For such reasons, the CPM seems to be a very promising tool for the optimization of the features of the sub-arrayed beams also with arrays of very large dimensions.
