Research of transducer array directivity based on different array elements
Yan Bi-ge · Journal of Northwest Normal University · 2011
Line array is made up of circular,circle ring-like and rectangular piston acoustic source as array element,the directivity functions about three kinds of array are obtained,and the contrastive analysis on its directivity is made.The results show that the array element shape,the spacing,the size,the number have certain influence on the directivity,in the same situation,the directivity of line array composed of circle ring-like array element is most superior.
