A novel beam scanning technique in time modulated linear arrays

In this paper, a novel technique for electronic beam scanning in TM linear array is proposed. This technique is realized at the first positive sideband. By controlling the duration of "on" times of each element the desired pattern can be synthesized and by adjusting the switch-on time instant of each element, the electronic beam scanning can be realized. Differential evolution strategy (DES) is employed to control the SLL at the first sideband and improve the first SBL simultaneously.
