摘要
介绍了独立分量分析的基本原理和以峭度为目标函数的独立分量提取算法的梯度算法,并通过实例说明了利用独立分量分析对声发射信号进行分析的方法,验证了独立分量分析技术在声发射信号分析方面的优越性和实用性,表明独立分量分析在声发射信号处理等领域有着巨大的应用潜力。
The fundamentals of independent component analysis is introduced, also is the gradient arithmetic whose object function is kurtosis. With typical examples, analysis method based on independent component for acoustic emission （AE） signals is illustrated. Also, it is validated that the technique of independent component analysis is perfect and practicable on AE signals analysis. All of these show that independent component analysis technique has enormous potential in the signal processing area of AE.
