摘要
声学传感器阵列设计的合理性直接影响声学层析成像系统对温度场重建质量。本文对声学传感器阵列的数量、布局等参数进行设计,利用计算机对不同结构下的传感器阵列进行仿真,比较了几种模型温度场的重建结果,初步确定了传感器阵列各参数的最优值。通过对声学传感器阵列的仿真设计,提高了声学层析成像系统的性能,据此参数设计的声学传感器阵列获得了较高的温度场重建精度。
The rationality of the acoustic sensor array design directly affects the acoustic computer tomography system for temper-ature field reconstruction quality.In this paper,the parameters such as the number and layout of acoustic sensor array have been optimized.The acoustic sensor array with different structures was simulated using the computer,the reconstruction results of the temperature field of the several models were compared and the optimal value of parameters of the acoustic sensor array was deter-mined primarily.Through the acoustic sensor array simulation,the performance of the acoustic computer tomography system is improved.High accuracy of reconstruction was obtained using the acoustic sensor array based on the parameter design above.
