摘要
GPS监测数据易受到多路径效应、温度变化以及噪声的影响,使得监测数据中混杂多类噪声,无法直接用于变形分析。为了提取真实的变形信息,需要对监测数据进行滤噪处理。该文通过小波分析的方法,对苏通大桥的GPS监测数据进行滤噪处理,结果表明小波分析能够有效的去除监测数据中的噪声。
GPS monitoring data is easy to be affected by multipath effects,temperature change and noise.So the monitoring data is mixed many noise,and it cann＇t be used to deformation analysis derectly. In order to extract the real deformation information,it is necessary to deal with the monitoring data by wavelet denoising. In this paper,based on the method of wavelet analysis,the GPS monitoring data of Sutong bridge is denoised. The result shows that the wavelet analysis can remove the noise of the monitoring data effectively.
