| 摘 要： | 在滑坡监测数据的分析中,噪声滤波是一项重要的工作,特别是滑坡变形系统处于混沌态时,混杂在混沌动力系统中的噪声信号,会掩盖系统的内在动力学特性,影响对系统的准确分析和预报.通过对监测混沌序列和噪声的小波分析,滑坡监测混沌信号的小波变换具有自相似性和噪声随分解尺度变化特征,混沌性质信号的小波变换和原信号在一定的尺度范围内具...

| Abstract: | In the landslide monitoring data analysis,the noise filtering is an important work,especially landslide in the state of chaos system,the noise signal mixed in chaotic system,which will cover the inner dynamics characteristic of the system,and affect accurately analysis and prediction of the system.Based on the wavelet analysis of chaotic sequences and noise of landslide monitoring,chaotic signal of the landslide monitoring has self-similarity with wavelet transform and noise characteristics change with scal... |
