离散多基元声基阵指向性函数计算

Calculation of directivity function for distributive acoustical arrays consisted of multielement transducers

摘要: 本文从任意分布的离散多基元点阵的指向性函数,引出线列阵、圆弧阵、平面阵、圆柱阵以及球面阵、共形阵的指向性函数。并且进一步阐述了它们的波束形成和波束空间复盖方案设计。

Abstract: This paper has given directivity function of arbitrary distributive array, consisted of separating multielements, derived the directivity function for linear array, circular array, plane array, cylindrical array, spherical array, and explained the principle of their beam forming and beam space covering.
