Abstract
An electromagnetic exploration method using a full-coverage anti-interference artificial source, comprising the steps of: (1) determining the scope and location of the measuring area; (2) field-exploring to determine the location of the transmitting source and the angle of the transmitting antenna; (3) calculating the maximum polarization direction angle of the electric field generated by the antenna at each measuring point; (4) arranging electric field sensors according to the polarization directions; (5) calculating the apparent resistivity of each measuring point. The method of the present disclosure obtains the earth resistivity using the reliable data with high signal-to-noise ratio. The field construction is flexible and convenient, the construction efficiency is high and the cost is low. The present disclosure provides a new development direction for the electromagnetic exploration.
