摘要
阐述了多尺度分析和小波变换的基本原理,分析了选择不同小波基对GPS动态监测数据去噪的效果。试验结果表明,小波变换实现了对GPS动态监测数据的有效去噪,是一种可靠的分析方法。
Multi-scale analysis and wavelet transform theory are discussed. Different wavelet basis and scale are analyzed to the denoise of GPS dynamic monitoring data analyse. Experimental results show that wavelet transform is an effective and reliable denoise-method to the GPS dynamic monitoring data processing.
