The
analytic signals of the magnetic tensor gradient within two-and
three-dimensional space can be applied as a useful tool to estimate the
depth and position sources because its value characteristics only depend
on location but magnetization direction of the sources of the magnetic
anomaly [7]. In this paper, we present results of the study for
application of the combination of derivatives of directional analytic
signals of the magnetic tensor gradient to determine the edges of the
sources through the new function Edge-detector (|ED|). Algorithms and
programs written in the Matlab language have been used for test
calculation on 3D models in correlative comparison with the method using
the amplitude function of analytic signals ([2]). The calculation
results showed the advantages of the new function |ED| and its
applicability in determing the boundaries of sources of magnetic
anomaly.
