摘要： To solve problems with conventional art, the present invention aims to significantly reduce measurement time for electrical resistivity profiling and logging without degrading the quality of the measurement by simultaneously transmitting a current from multiple points to underground and carrying out mathematic processing to calculate a potential obtained when a current is transmitted independently from any transmission point, based on observed response potential waveforms. At simultaneously transmission from multiple points, such current waveforms as zero the covariance thereof are selected. Then, a possible response obtained independently at transmission point can be determined by dividing the covariance of the observed potential waveform and the current waveform by the variance of the current waveform. As the waveform zeroing the covariance, an M-sequence code with zero added to the end thereof is applied.

摘要： A ground exploration system (5) comprising:
- a generator (6) configured to inject a non current-regulated and 100% duty cycle injection current Ii(t) over time t into the ground structure (1), and
- a processing unit (7) configured to measure a corrected induced polarization of the ground structure (1) during at least one pulse duration of the injection current by:
∘ measuring a ground tension Vg(t) over time t,
∘ registering the injection current Ii(t) over time t,
∘ applying a transfer function TF to the injection current Ii(t) and to the ground tension Vg(t) and compute an impedance function IF such as IF = TFVgtTFIit,
∘ applying the transfer function TF to a square pulse of a theoretical regulated current It(t) over time t and to compute a corrected tension Vc(t) over time t such as Vc(t) = TF-1 (IF ∗ TF(It (t))),

wherein the processing unit (7) is further configured to determine the at least one electrical property based on the corrected induced polarization of the ground structure (1).
