中文说明：
现今阵列应用中，宽带信号的处理越来越多。由同心圆阵组成的多圈圆形阵列在宽带信号处理上有更强的优势。和单圈均匀圆阵相比，同心多圈圆阵的嵌套设计阵列工作频率范围更宽，同时，灵活性增强。
English Description：
In today's array applications, broadband signal processing is more and more. The multi circle circular array composed of concentric circular array has stronger advantages in broadband signal processing. Compared with the single circle uniform circular array, the nested design of concentric multi circle circular array has wider frequency range and enhanced flexibility
