A combined amplitude-density synthesis approach for the design of linear aperiodic arrays

A new iterative procedure for the design of linear aperiodic arrays is introduced which permits exploiting, in a combined way, both the positions and the excitation amplitudes of the array elements obtaining a pattern which optimally fits, in terms of a weighted L2 norm, the pattern of a reference linear continuous aperture. Interesting radiative properties and some advantages for the realization of active arrays will be presented as well.
