Inverse Spline Interpolation for the Calculation of All-Time Resistivity for the Large-Loop Transient Electromagnetic Method

XIONG Bin (School of Info-Physics & Geomatics Engineering, Central South University, Changsha410083, China)  
A convenient and fast numerical calculation method of all-time apparent resistivity for the transient electromagnetic methodinverse spline interpolation method has been developed. Several conversion examples, from induced electromotive force through central-loop TEM2.5-D forward program to apparent resistivity, illustrate the feasibleness of inverse spline method. At the same time, the method has also laid the foundations of initial model definition in TEM automatic inversion.
