Application of wavelet multi-scale analysis in gravitational survey

Wavelet multi-scale analysis is widely used in data processing of geophysics. It is able to help geophysicists to solve a lot of difficult problems in gravitational and magnetic survey. Its theoretical basis is illustrated at first. Multi-scale analysis and Mallat algorithm are introduced as follows. Three gravity models are designed and its wavelet multi-scale analysis results are discussed. Conclusions are made finally.
