Locating magnetic sources by Empirical Mode Decomposition

Several noisy and noise free synthetic models have been used to verify the efficiency of Empirical Mode Decomposition. Besides, for a real test, magnetic data from Sourk mining area in Central Iran have been utilized. Some other location detector and edge detector methods, including Horizontal Derivative, Total Gradient, Tilt Angle and Enhanced Horizontal Derivative methods, have been applied to synthetic and real magnetic data to compare with results of CEEMD. The results show that, in the existence of relatively high level of noise (usually more than 3%), the improved version of Empirical Mode Decomposition, i.e.,Complete Ensemble Empirical Mode Decomposition method (CEEMD) has an acceptable resolution in locating magnetic sources. Generally, comparing with some other methods, applying Empirical Mode Decomposition may lead to more reliable locating adjacent magnetic sources with fewer artifacts especially in noisy magnetic data.
