摘要：
Frequency domain helicopter-borne electromagnetic survey Is still in the stage of research and testing in China. Due to the lack of effective means of data processing, further application and development of this technology is limited. After a brief introduction to the Marquardt's algorithm in this article, we successfully applied it in the processing of frequency domain aero electromagnetic (FAEM) data, and several key technologies such as Jacobian matrix calculation, the initial model assignment, the shape model and physical properties model inversion are also discussed. Finally, the method is used in some theoretical models and field data, the result is satisfying and believed to be helpful for the interpretation of FAEM data.
