The receiver electrodes are also multiple and simultaneously measured by using a multiple receiving function. Electric fields of these frequencies are separated in frequency domain at a receiver electrode and each transmitter electrode is identified by each respective frequency. The key characteristic to speed up the measurement is that the system transmits multiple currents of different frequencies from different transmitter electrodes simultaneously. Summary A new resistivity survey system, which is capable of very fast data acquisition as compared with conventional DC resistivity systems, has been developed. Observed and calc.ulated apparent resistivity Observed data is shown in Figure 6, together with The An example of the spectrum of received s.erved resistance value at potentialĮlectrode pairs with respect to each current electrodeĪ resistivity model obtained by 2D inversion of the It has eight transmitters and eight receivers.
