| 摘 要： | 考虑到小波技术在粗差探测、消噪方面有特殊的作用,本文结合实际算例,把小波分析与传统数据处理技术结合作为研究对象,提出一种基于小波消噪的时序分析改进法。并对这种处理方法在GPS监测中的应用作了充分地论证。结果表明,经过小波处理后,时序分析法在预报方面有明显的进步,小波处理后的时序分析法比小波处理前的精度高,从而说明了这种改进方法的可行性。

| Abstract: | Considering the special function of Wavelet technology in gross error detection and noise reduetion, the paper presents an improved timeseries analysis method based on Wavelet noises reduction focused on the combination of Wavelet technology and traditional data processing technology, The application of this method for GPS deformation monitoring is demonstrated by a practical example. After being processed by Wavelet, the result of this method verified its notable advancement on deformation analysis and forecast . The accuracy is much higher than unimproved timeseries analysis method, which tells us the feasibility of the improved method. |
