R-D算法 产生数据的m文件 是最简单的情况 不弯曲不走动(R-D algorithm to generate m file data)

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.)
