Abstract :
The differential evolution (DE) algorithm is applied to the synthesis of low sidelobe linear antenna arrays. Simulation results of several canonical problems are presented and compared to those optimized by a real-coded genetic algorithm (RGA). It is observed that the differential evolution algorithm outperforms the real-coded genetic algorithm for low sidelobe array synthesis.
