Do you really understand the "full true 3D excitation polarization method"?
Most of the methods of excitation polarization are receiving dipole measurement methods. The number of channels is limited. It must also be arranged according to the regular dipole direction. In particular, the conventional two-dimensional method and the conventional three-dimensional method are traditional dipole receptions. Restriction, the amount of measurement data is small, the signal-to-noise ratio is difficult to guarantee; and this time we focus on the full-true 3D excitation polarization method, using a unipolar measurement method, sharing a common reference line (CVR), between any two receiving points Dipole measurements can be made up. This method can perform channel expansion without limit, and the effective data volume obtained is more than 10 times that of the conventional three-dimensional method.
If a 6*6 grid is placed, during the same acquisition time:
The conventional two-dimensional method gets 30 valid data.
The conventional 3D method gets 60 valid data.
The full-true 3D method yields 654 valid data.
Introduction of full-true 3D induced polarization
Field layout: all receiving points are fixed, and at the same time, the transmitting electrodes are moved one by one. The main station performs real-time condition monitoring and real-time data display, including GPS status, battery working status, grounding resistance, Vp primary field, time series data, and so on.
