针对孔型缺陷的自适应滤波应用研究

为了准确检测出工件内部由于噪声影响存在的孔型缺陷,本文通过分析自适应滤波原理,运用自适应滤波去噪方法对存在孔型缺陷的工件的回波信号进行去噪处理;噪声杂波被有效滤除,效果明显。

In order to detect the signal of the Hole defects around the noise in the specimen accurately. This article analyze the principle of the adaptive filtering, uses the filtering denoising signal processing methods to removel the noise of the Echo signal. It is obvious that the noise is removed.
