- Abstract:

We explain a multi-scale analysis of wavelet theory and Mallat Algorithm.In view of the previous slow pace of implementation for MATLAB files,We propose a new mixed programming technique to call C++ source process using MEX file in MATLAB environment.We make a calculation and comparison of magnetic anomalies superposition of the sphere theoretical model,and using the method to decompose the aeromagnetic anomalies of a certain measured area and its surrounding areas,we get two orders of the typical characteristics of aeromagnetic anomaly map.The results show that detail of aeromagnetic anomaly map obtained through wavelet decomposition also plays a role in the power spectrum analysis.The deep faults can be located on the anomalous map,hence,this map provide a reference for the similar regional data processing in future.
