在高精度磁测数据处理中小波分析方法能够同时提取不同尺度地质体的数据特征,便于对感兴趣的数据特征进行进一步的处理、分析、解释,排除与目标地质体特征数据无关信息的干扰。在模型分析的基础上,对内蒙古某地实际资料进行了处理,其结果与航空γ能谱异常及地质资料相吻合。

WT5”BZ] In high precision magnetic data processing, wavelet analysis can simultaneously extract data features of geologic bodies with different scales so it facilitates further processing, analysis and interpretation for the features of interest, and interference can also be eliminated. After model analysis,the real data from Inner Mongolia were processed. The results matches well with anomalies of airborne γ energy spectrum and geological data.
