An efficient electronic beam steering technique in time modulated linear array (TMLA) is proposed, where the first positive and negative sidebands are utilised to implement the electronic steering process. In this technique, new periodic time sequences are used, in which a positive-ON, negative-ON, and OFF durations are utilised to obtain high sufficient steering in TMLA. Furthermore, it is shown that by using these time sequences, the non-steerable array pattern at the fundamental frequency and also the even sidebands can be eliminated and nulled to zero. In addition, the radiation power and the directivity of this proposed steered-TMLA are formulated in their closed form. The genetic algorithm is implemented to optimise the steered-TMLA by suppressing the remaining odd sidebands and increasing the power radiation at the first positive and negative sidebands.

时间调制线性阵列中的高效电子束转向方法

提出了一种有效的时间调制线性阵列（TMLA）中的电子束转向技术，其中第一正负边带用于实现电子转向过程。在此技术中，使用了新的周期性时间序列，其中使用了正导通，负导通和关断持续时间来获得TMLA中的足够高的转向。此外，示出了通过使用这些时间序列，可以消除基频处的不可转向阵列图案以及偶数边带，并将其归零。此外，此拟议的定向TMLA的辐射功率和方向性以封闭形式制定。
