The relationship between local wavenumber and analytic signal in magnetic interpretationLocal Wavenumber and Analytic Signal

Abstract Recently, a number of automated methods for source location from 2D (profile) magnetic data have been developed, based on either the local wavenumber (Thurston and Smith, 1997; Smith et al., 1998; Thurston et al., 2002; Salem et al., 2005; Smith and Salem, 2005) or the amplitude of the analytic signal (Hsu et al., 1996; Bastani and Pedersen, 2001; Salem and Ravat, 2003; Salem et al., 2004; Salem, 2005). The main advantage of using …
