| Abstract: | In this paper the Capon spectral estimation method,i.e.the maximun likelihood method,was applied to the analysis of the short periodic geomagnetic events occurred from January to March,1986 at the Chinese Great Wall Station on Antarctic(CGWSA) and the complex transfer functions A and B for Peneds T=45 s-160 min were calculated,derived from the medulus|A| of A and its phase angle,it seems that there are two structural layers in the subterranean electric conductivity under the CGWSA,the corresponding periods at the interface being around 20-26 minutes.We also compared the Capon spectral estimation method with the Fast Fourier Trasformation(FFT).The former appeared to be better than the latter. |
