| 摘 要： | For magnetotelluric sounding (MT), many processing methods based on power spectrum have put forwardlots of hypotheses, such as MT signals are Gaussian, linear and minimum-phase. If practical signals do not satisfythese requirements, the results will have a few problems as follows. Firstly, when signals are non-linear andnon-Gaussian, the information of the earth contained in the MT signals cannot be sufficiently extracted; Secondly,when signals are non-Gaussian and non-minimum phase, the p… |
