Abstract
A WEM-based method for deep resource detection using sky waves refers to the technical field of deep resource detection. The proposed method of deep detection using sky waves improves the traditional 'atmospheric-lithosphere' half-space propagation theory into a full-space 'sky wave' theory of “ionosphere-atmosphere-rock layer”, that is, the influence of the ionosphere and the displacement current in the air are taken into consideration to obtain a new precise expression of “sky wave” response, which is suitable for full space, slow attenuation and long distance propagation. A receiving device for sky wave signal has been developed. Through theoretical model calculation and actual data measurement, it is known that it is possible to use the sky wave for detection within the scope of China's national territory to realize the high-precision electrical structural exploration within a depth of 10 kilometers and open a new era of artificial source electromagnetic detection.
