Abstract:

 In this work, concentric ring Arrays (CRA) with non-uniform excitation are investigated, with the objective being to minimize the Sidelobe Level (SLL) for the array and keep the Directivity within an acceptable value The optimization technique to be used to reach this objective is the spiral inspired optimization technique First, the technique is used to minimize the SLL only Next the array factor is optimized for Directivity only Then, the excitation is varied for both SLL and Directivity to be optimized The results show significant improvements with respect to the uniform case, especially for SLL reduction, with different levels of success depending on the employed optimization technique, fitness function, varied parameters, and array size.
