采用GPS进行高层建筑物实时动态观测被认为是有效的方法,如何处理海量GPS振动观测数据是一个重要的问题。本文根据GPS振动观测数据特点,将小波分析技术应用于GPS振动观测数据处理,研究了不同小波基、分解尺度、阈值选择对观测数据去噪的影响,获得了有益的结论。
Real-time dynamic observation of tall buildings using GPS is considered as an effective method. How to deal with the massive GPS vibration observation data is an important issue. According to the characteristics of GPS vibration observation data, the wavelet analysis technology is applied to GPS vibration observation data processing. The effects of different wavelet bases, decomposition scales and threshold selection on the observation data denoising are studied. Some useful conclusions are obtained.
