摘　　要：以圆形活塞声源为阵元,构建了圆形换能器阵列和交错圆形换能器阵列,求出了2种阵列的指向性函数。用Matlab对阵列的指向性进行可视化,得出2种阵列的指向性特点,对比了指向性优劣,并讨论了阵列指向性随阵元半径和组阵参数的变化关系。此研究对换能器阵列的设计有一定的参考价值。The circular transducer array and the Interlaced circular transducer array are constructed with the circular piston sound source as the array elements,and the directivity functions of the two arrays are of the two arrays are o of the two arrays is visualized by using Matlab,and the d.The directivity of the two arrays is compared. The relations y characteristics hip between the directivity of the arrays and the radius of the array elements and the array parameters is discussed.This research has some reference value for the design of transducer array

关 键 词：圆形换能器阵列 交错圆形换能器阵列 指向性 阵元
