Amplitude weighting at the subarray outputs alone causes grating lobes in array factors. An approach that disrupts the periodic quantization by dividing the array into subarrays of unequal sizes and amplitude weighting at the subarray ports is presented. A hybrid genetic algorithm optimizes the subarray size and subarray weights to minimize the maximum sidelobe level.
