| 摘 要： | 相关的概念是为研究随机信号的统计特性而引入的,相关性可以用来描述为两组信号的相似程度,超声在介质中传播会产生多次反射波,通过计算各次波的相关系数,可以获得超声在介质中的传输时间,从而得到介质的厚度.

| Abstract: | the concept of correlation is to investigate the statistical properties of stochastic signal, introduced correlation can be used to describe the similarity degree of two groups of signal, ultrasonic propagation in the medium generates multiple reflection waves, by computing the correlation coefficient of every wave, ultrasonic transmission time in the medium can be obtained, and the thickness of the medium is obtained. |
