EnglishSAR spaceborne applications typically employ conformal phased array antennas consisting of a great number of elements, which are required to generate many shaped beams, including nulls and side-lobe regions with complicated shapes. In such applications, only the pattern amplitudes are of concern, thus power synthesis procedures are required. In this paper we will use a projection based method, for solving a power synthesis problem for a conformal phase-only reconfigurable array, which offers the important additional capability of reducing both the DRR of the excitations, and the amplitudes of the cross-polar patterns. Finally the problem is also solved using a genetic algorithm, and the results are then mutually compared.

| Abstract: | SAR spaceborne applications typically employ conformal phased array antennas consisting of a great number of elements, which are required to generate many shaped beams, including nulls and side-lobe regions with complicated shapes. In such applications, only the pattern amplitudes are of concern, thus power synthesis procedures are required. In this paper we will use a projection based method, for solving a power synthesis problem for a conformal phase-only reconfigurable array, which offers the important additional capability of reducing both the DRR of the excitations, and the amplitudes of the cross-polar patterns. Finally the problem is also solved using a genetic algorithm, and the results are then mutually compared. |
