Design of Thinned Arrays Based on Genetic Algorithm

Abstract

Genetic algorithm (GA) is employed for thinned array synthesis in this paper, and the side lobe level is used as the optimization target to optimize the position of the array elements. The simulation results show that the −17dB side lobe level is achieved under the condition of 50% sparse rate, which verifies the effectiveness of the algorithm. By adopting thinned array, the channel number of phased arrays is reduced, thus reducing the antenna cost.
