| description | The digital linear filter method is used to compute the normalized vertical magnetic field for a circular loop in CFS system. Three-layer earth models with resistive and conductive basement are considered. The corresponding field expressions are suitably written, and the multifrequency response is computed and presented in convenient forms.
Analysis of theoretical data indicates that for highly resistive basement, the variation in layer conductivity and intermediate layer thickness is well reflected on three-layer amplitude response curves at low frequencies and at high conductivity contrasts between first and second layers. This, however, is not true in the case of conductive basement, where the resolution of the intermediate layer is observed to be comparatively poor. The resolution of an intermediate conductive layer in a three-layer sequence is found to be satisfactory. |
