Abstract
This study suggests a new edge-detection filter, called enhanced total horizontal derivative of the tilt angle (ETHDR). ETHDR is the total horizontal derivative of the ratio of the vertical derivative to the total horizontal derivative of the first order analytical signal amplitude. This paper compares the results of ETHDR and other normalized derivative filters. The feasibility and capability of the ETHDR method is demonstrated using a theoretical data and a real magnetic dataset. Compared with the other derivative based filters, the ETHDR produces more detailed results for deeper magnetized structures and gives sharp response over edges of sources.
