Abstract

Separation filtering of magnetic data can be extended from simple regional/residual<br>separation to the general multilayer case it is theoretically possible to design filters to<br>deconvolve the effects of causative sources occurring around a particular level. The problem<br>posed is non-linear since the field equations contain terms relating to source width and<br>thickness as well as source depth.<br>Separation filtering becomes very difficult when there is considerable overlap in the spectra<br>of individual depth ensembles. The degree of separation achieved depends on the depth<br>difference and the spectral b/B ratio, the ratio of the amplitudes of the shallow and deep<br>ensembles. A high b/B ratio is needed if the fîltering objective is to deconvolve the effects of<br>shallow sources with minimum contamination by deeper sources.
