TEM intensive sampling with wavelet transfer analysis and its engineering application

瞬变电磁(TEM)是一项发展中的应用地球物理技术.通过对TEM数据密集采样以及小波分析(解)处理,为TEM提高探测分辨率和提升探测深度提供了理论基础;采用小波多尺度分解和小波基的自适应选择,实现了非平稳TEM密集采样信号的小波分析处理.文章还对早期道和晚期道数据处理进行了探讨,从方法上提升了数据处理的应用质量.工程实践表明,TEM密集采样及小波分析处理技术具有较为广泛的工程实用价值和技术推广价值.

TEM is an increasingly developing technology.Intensive sampling and its wavelet transfer provide a theoretical basis for improving resolution and detecting depth.Using wavelet decomposition and wavelet multi-scale adaptive selection,the adoptable analysis of adoptable wavelet transfer of intensive sampling of non-stationary occured.The early and late channel data processing method was discussed.The result indicates that its potential value is important in extending and applying in engineering area.
