New Filter for Calculation of Current Density Pseudosections from VLF Dip Angle Data

P028 NEW FILTER FOR CALCULATION OF CURRENT DENSITY PSEUDOSECTIONS FROM VLF DIP ANGLE DATA Abstract 1 VLF is one of popular electromagnetic prospecting techniques. In spite of easy data acquisition it’s data interpretation is complicated and there is not a certain method for it. Current density pseudosections that can be calculated by raw data filtering are good tools for preliminary interpretation. In this research we proposed a new approach for obtaining them. Introduction Current density pseudosections are known in EM data interpretation and they are usually constructed by linear filters theory (Karous & Hjelt 1983). These filters can calculate current
