Synthesis of Uniform Amplitude Thinned Linear Phased Arrays Using the Differential Evolution Algorithm

This paper proposes an effective approach based on the differential evolution (DE) algorithm for the synthesis of uniform amplitude thinned phased linear arrays. Two different measures are introduced in the algorithm for the constraint of the search ranges of the element spacing, and quantized phase excitations are also considered for array feeds with digital devices. Simulation results of several typical phased array problems are compared with those simulated by the real-coded genetic algorithm (RGA) to demonstrate the effectiveness of the proposed approach.
