Forward and inversion algorithm of magnetic interfaces using two-interface pattern Parker method

Key words:  two-interface pattern  interface inversion  magnetic inversion  Parker method

Abstract:

Forward and inversion formulae of two-interface pattern was deduced，and an approach to solve inverse divergence was proposed. The key issues and techniques about implementation of Parker method were analyzed. The precision and usability of the method were proved through the model examination. The results show that the method can promise inversion converge stably. The method has high calculation precision and the absolution of error ranges from 0. 01% to 4%. The method also has antinoise property. Furthermore, the method was used to process field magnetic data of somewhere in China and the inversion results are reasonable.
