有关于Matlab图形功能的详细讲解，为PPT版，相信对广大师生会有所帮助。(Have on the Matlab graphics features of detailed briefings for the PPT version, I think it would be helpful to teachers and students.)

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。 (Nowadays array applications, the broadband signals in many more and more treatment. By the array composed of many concentric circular ring array of broadband signal processing at up there is more advantage. And single-lap compared to uniform circular array, circular array concentric circle many nested design frequency range of a broader array of work at the same time, enhance flexibility.)
