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.
