APPLICATION OF HILBERT TRANSFORMS TO MAGNETIC PROFILES

Abstract

Three related operations commonly performed on total‐field magnetic data are 1) conversion to vertical‐field anomaly, 2) reduction to the pole, and 3) computation of pseudogravimetric anomalies. This note shows that for profile or flight line data for which the source can be assumed to be two‐dimensional, all these operations amount to linear combination of the profile with its Hilbert transform.
