Abstract

The influence of ionosphere and displacement current can not be ignored in earth-ionosphere mode.This leads to a highly oscillating kernel function and it's hard to get accurate results using traditional fast Hankel transform(FHT) method.This paper attempts to solve this problem using quadrature with extrapolation(QWE) method which Kerry Key proposed in 2012.First,this paper uses analytical solution of CSAMT in uniform half-space to verify the accuracy of this algorithm, then compares calculation results of three-layer model in earth-ionosphere mode with several groups of filter coefficients.It is found that the effect of QWE is much better than FHT.
