说明：  信号处理是结构健康监测系统一个重要组成部分。小波变换作为有效的信号处理工具能对被分析信号进行更细致分析，获得比傅立叶分析更多的信号特征。将小波分析应用于航空结构材料的结构健康监测中，对检测信号进行时频局部化处理，获得与结构状态相联系的特征。
(Signal processing is a structural health monitoring system an important part. Wavelet transform as an effective signal processing tools can be a more detailed analysis of signal analysis, Fourier analysis of more than the signal characteristics. Wavelet analysis to the structural materials used in aviation structural health monitoring in the detection signal processing time-frequency localization, and structure was linked to the characteristics of the state.)
