摘要
推导出了声参数变化时的信噪比增益与结构噪声相关函数的关系。探讨了一种简单情况下的空间平均处理,得到了相关函数和信噪比增益的表达式,与实验结果符合良好。
The relation between the signal-to-noise enhancement and the correlation function of the structure noise for varying acoustic parameters have been deduced. Spatial averaging in a simple case has been discussed and expressions for the correlation function and the signal-to-noise enhancement have been obtained. The calculated results are in good agreement with the experimental results.
