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.
