The method of array synthesis is used in radar cross section (RCS) reduction of an array antenna, and the radiation performance and low scattering property of an array antenna are optimized by adjusting the element spacing of a non-uniform array. The differential evolution (DE) algorithm is adopted as the optimization tool, while the method of moments (MoM) is applied to calculate the radiation and scattering parameters of each candidate solution. The objective function for combining antenna radiation with scattering is used to synthesize an array with a low side lobe and low scattering property. Finally, the optimization examples of the dipole and bowtie show that the array RCS can be reduced more than 5dB by this method.

Key words: array synthesis, differential evolution algorithm, method of moments, RCS reduction
