Abstract

The Spectral Induced Polarization (SIP) method delivers more important information about the subsoil than the DC-Geoelectric method can. To improve the progress in measurement of the SIP method Multi-Receiver Instruments are used. In addition we have introduced the Multi-Transmitter Technique, from which we expect a further acceleration. As a first step towards routine use, we implemented and tested a novel time series analysis algorithm and expanded the hardware of one of our Multi-Receiver SIP Instruments (type SIP256C, Radic Research) with an additional independent transmitter. Two types of signals were investigated: (a) different frequencies and (b) phase modulation. First results show that both techniques have their individual advantages. The evaluation of a multi-frequency signal is easier, the use of phase-modulated signals seems to allow faster measurements.
