【摘要】：时间反演(TR)是一种新型的电磁波传播与控制方法,具有电磁环境自适应性。采用时间反演方法,可使结构复杂的天线阵列方向图综合设计简单化。该文初步探索了将时间反演方法应用于微带天线阵列激励设计的可行性,并进行了数值模拟和实验验证。结果表明:对于不同的主波束指向,时间反演法均能准确地确定其对应的激励分布。相对于传统的激励分布确定方法,时间反演法无需互耦补偿计算,准确便捷,且不受阵列和阵元结构形式的限制,在结构复杂阵列的激励分布计算上优势明显。
[Abstract]:Time inversion (tr) is a new method of electromagnetic wave propagation and control, which is adaptive to electromagnetic environment. The method of time inversion can simplify the synthetic design of antenna array pattern with complex structure. In this paper, the feasibility of applying the time inversion method to the design of microstrip antenna array excitation is preliminarily explored, and the numerical simulation and experimental verification are carried out. The results show that the time inversion method can accurately determine the corresponding excitation distribution for different main beam directions. Compared with the traditional method of determining the excitation distribution, the time inversion method does not need mutual coupling compensation calculation, is accurate and convenient, and is not limited by the structure form of array and element, so it has obvious advantages in the calculation of excitation distribution of complex array.
