| 摘 要： | 本文使用稳相法详细讨论了圆弧阵的水平指向性,给出了计算指向性函数的主瓣束宽和主瓣内平均声压的比较准确的公式。本文提出的幅度束控方法和设计不等距阵方法可以成功地克服圆弧阵主瓣内指向性函数起伏大的缺点,同时使主瓣束宽和主瓣内平均声压基本保持不变。

| Abstract: | In this paper horizontal directivity of arc array is discussed detailly by Using stationary phase method and more accurate formulae of mainbeam width and average pressure within mainbeam are given.The methods of amplitude shading and unequally spaced array given in this paper can successfully used to resolve the problem concerning the more obvious fluctuation of directivity functions within the mainbeam,and at the same time keep the mainbeam width and average pressure within the mainbeam approximately constant. |
