The possibility of an instantaneous resistivity profiling by the simultaneous multi channel current injection using CDMA method (I: The principle and the basic experiment)

Abstract A new method of resistivity profiling measurement is proposed. The method is based on CDMA (Code-divided-multiple-access) technology to allow simultaneous current injection which can reduce the measurement time dramatically. The principle and simulation result is presented with simple experiment, which shows possibility of this method.
