小波分析在GPS振动监测数据中的应用

摘要

The wavelet transform theory and principle of wavelet denoising are discussed. Forthermore three dif ferent denoising method for GPS dynamic monitoring data denoising are analyzed. The experimental results show that the wavelet transform especial soft threshold denoising method is an effective method for the GPS dynamic moni toring data processing. It can improve the accuracy of monitoring data.%分析采用三种不同去噪方法对GPS动态监测数据去噪的效果.结果表明:对GPS动态观测数据序列采用小波去噪尤其是软阈值去噪方法可以有效地消除随机噪声,提高监测数据的精度.
