Abstract
The disclosure pertains to the field of electromagnetic exploration, and in particular relates to a device and method for ground source transient electromagnetic near-field detection and related device, with the purpose of solving the problems that the method for loop source transient electromagnetic detection has a relatively small detection depth and weak signals. The device of the disclosure includes an excitation source emitting device and a receiving device for signal detection. The excitation source emitting device includes an emission source, the emission source is a grounded conductor wire; the grounded conductor wire is used to convert a bipolar pulsed current into an electromagnetic field to be emitted underground; and the receiving device is configured for detecting a magnetic field and/or electric field signal in a survey line segment of an observation range of the grounded conductor wire using the method of areal sideline scanning survey.
