The Total Component (or vector magnitude) and the Energy Envelope as tools to interpret airborne electromagnetic data: A comparative study

摘要

This paper is a comparative study of the Energy Envelope and the T-component response for interpreting airborne electromagnetic (AEM) data. The Energy Envelope is the square root of the sum of squares of three component AEM data along with their Hilbert transforms, while the T-component response is a similar quantity, except without the Hilbert transform terms. These quantities can be used to determine approximate geometrical parameters of compact anomalous targets. The approximate parameters are useful for constraining automatic interpretation algorithms.
