Due to remarkable errors caused by the limited data-processing capacity and the low precision of curved surface data, the processing and transform methods for the curved surface potential field have seldom been used in practical work. In this paper,a frequency domain dipole layer method for the processing of aeromagnetic data of curved surface,together with the reducing noise means, is put forward. This method was used in the aeromagnetic area of Huangshi,Hubei Province. A comparison of the calculated data with the surveyed data shows that the result is satisfactory and the magnetic field is in accord with the magnetic body. It is obvious that the frequency domain dipole layer method has good practicality,and can hence be used to process the aeromagnetic data of curved surface.
