An improved method for reduction to the pole of magnetic field at low latitude—the method of frequency conversion bidirectional damping factor

LIN Xiao-Xing1,WANG Ping2 1 School of Geophysics and Information Technology,China University of Geosciences,Beijing 100083,China 2 China Aero Geophysical Survey & Remote Sensing Center for Land and Resources,Beijing 100083,China  
This paper reviewed and analysed the commonly used damping factors,and then brought forward a method for rebuilding the damping factor,that is,the frequency conversion bidirectional damping factor(FCBDF).This factor not only presses amplitude spectrum,and rebuilds phase spectrum,but also supplements a frequency conversion factor.By tests on model data and actual data,it is proved that this method could get better result and highlight geological information.
