摘要
为使超声相控阵在输出平面上的声压输出达到较好的分布模式,本研究通过预先设定相控阵输出面上的声压分布形态,然后利用迭代算法来求解超声相控阵驱动向量,最终实现了超声相控阵在输出平面上声压输出的有效控制,并通过计算机仿真对这种算法进行了验证。
In order to achieve a relative good sound pressure distribution of ultrasonic phased array in the output plane,this paper will present a new method of how to optimize the output of the phased array.In this paper,the distribution of output acoustic field was predetermined and then the iteration solutions were utilized to solve the drive vector of ultrasonic phased array,under this theroy the output model of acoustic field could been controlled effectively.At last we verified the efficiency of this algorithm through computer simulation.
