A novel stepped-amplitude aperiodic phased array synthesis method is proposed. The presented technique is based on iterative convex element position perturbations and uses pre-defined excitation amplitudes. A 64-element irregular array with two discrete amplitude levels (0.5 at the edge-elements and 1 at the center-elements) is synthesized for demonstration purposes. The array achieves a side lobe level lower than - 30 dB and a directivity higher than 20 dBi within the given field-of-view (±60 degrees in azimuth and ±15 degrees in elevation). Through comparative studies of the array directivity, effective isotropic radiated power and maximal side lobe level with the ones of the uniformly-fed/amplitude-tapered periodic arrays and a uniformly-fed aperiodic array, it is shown that the proposed stepped-amplitude array provides the best complexity/performance trade-off.
