声对接阵阵元参数控制

Elementary parameter control of acoustic coupling array

提出对声对接阵阵元参数进行控制,以达到提高声对接阵系统精度的目的,并对由于阵元参数改变而引起对接基阵各个阵元之间的交叉耦合的影响以及阵元的近场声压进行了理论分析和计算机仿真计算,结果证明该方法是有效的.

A method of putting the elementary parameter of transducer under control is proposed in ordor to improve the precision of acoustic coupling array. The influence of elementary parameter change on the crossing-coupling of acoustic coupling array, and the near-field acoustic pressure of the elementary transducer are analyzed theoretically. Then the simulation and calculation are given. The result of simulation is in agreement with that of theoretical analysis. It is shown that the method is proven valid.
