Interpretation of marine magnetic anomalies. Part I. A survey of existing methods and analysis of the analytic signal method

In this work, the problem of interpreting linear marine magnetic anomalies in the context of the spreading model is considered. Analysis and a comparison of the methods proposed earlier for solving this problem are carried out and the analytic signal method is considered in detail. In terms of a simplest example, it is shown that the AS method has significant restrictions associated primarily with the size and/or occurrence depth of the bodies.
