Chapter 17 Extracting IP parameters from TEM data

摘要: Publisher Summary As the Induced electrical polarization (IP) technique provides very useful information about properties of geologic materials and time-domain electromagnetic (TEM) better field data acquisition, it is important to study extraction IP from TEM data. The knowledge behavior heterogeneous helps greatly in improving accuracy interpretation. response measured using a coincident loop system above dispersive conductive earth can show evidence effects that manifest themselves as negative (NR) phenomenon where transient voltage undergoes rapid decay, which followed by polarity reversal. regarded noise many practicing geophysicists eliminated their because there exists no convenient way inverting effect. Much research has been done on inversion EM measurements polarizable ground. A number methods have used for determining chargeability or frequency-domain an electrode system. Inversion developed estimating Cole-Cole parameters This chapter presents neural network approach finding half-space layered conducting targets central systems predict parameters.
