Embodiment Construction
[0043] The following is a further description of the present invention in conjunction with the accompanying drawings and specific embodiments
[0044] See figure 1 As shown, the present invention provides an artificial field source frequency domain electromagnetic apparent resistivity measurement method, which comprises the following steps:
[0045] Step S1: First, according to the exploration needs, set the appropriate field source position, and lay out a number of survey lines and corresponding observation points in the exploration area, place an electromagnetic signal receiver at the observation point, and place the signal transmitter at the field source position for the exploration. The area transmits electromagnetic signals of multiple frequencies;
[0046] Step S2: Use the electromagnetic signal receiver to record the potential difference V between the two measuring electrodes, the measuring electrodes are in the same orientation as the power supply electrodes, and reco...
