In phased array antennas, sidelobe reduction of the radiation pattern in the direction of the interference signals can be done by controlling either the complex excitations or the spatial phases of the array elements without affecting the main beam. However, the computation times become very large when an antenna with a large number of elements is analyzed. This paper presents a method of sidelobe reduction, which involves perturbing the locations of the subarrays.
