Abstract

PURPOSE:To obtain specific resistance data with a high S/N as a result by removing the three-dimensional adverse influence of a shallow part by two-dimensional or three-dimensional space filter arithmetic even when an underground electric structure is a three-dimensional type. CONSTITUTION:An electric field sensor 1 measures a varying electric field of two horizontal components at measurement points spreading in a plane which has enough density to sample the space variation of the electric field in an investigation area. At the same time, a magnetic field sensor 2 measures a magnetic field of two horizontal components at one fixed point. The a recording processor calculates the impedance as a function of the coordinates and frequencies of the measurement points from the measured electric field and magnetic field. Further, the apparent of real resistivity is computed from the impedance. Further, the two-dimensional and three-dimensional space filter to calculate a weighted mean electric field, weighted mean apparent resistivity, or the weighted mean real specific resistance from the impedance.
