摘要
阐述了小波变换在变形监测数据处理中的应用方法,将变形监测的数据序列视为不同频率成分组成的数字信号,用MATLAB编程实现小波分析对监测数据的粗差识别、消噪、发展趋势的提取,实例表明,小波分析可以较好地适用于大坝变形监测的数据处理。
Described GPS deformation data processing method based on wavelet transform. the data of deformation monitoring sequence as consisting of different frequency components of the digital signal is processed, with wavelet analysis of MATLAB programming, to achieve the gross errors of monitoring data, eliminate noise, trends extraction, examples show that the wavelet analysis theory applied to data processing of the dam deformation monitoring is practical and operational.
