主 题：skywave theory instrument development electromagnetic exploration deep resources
摘 要：Skywave refers to the electromagnetic wave reflected or refracted from the ionosphere and propagated in the form of a guided wave between the ionosphere and the Earth’s *** the skywave can propagate over large distances,it has been widely used in long-distance *** paper explores and demonstrates the feasibility of skywave for deep resource and energy exploration at depths of up to 10 *** and technical advancements were accomplished in furthering skywave applications.A new solution method based on Green’s function has been developed to study skywave propagation in a fully coupled lithosphere-air-ionosphere full space *** the first time,the model allows one to study skywave distribution characteristics in the lithosphere containing inhomogeneity such as ore deposits or oil and gas *** model also lays a foundation for skywave data processing and *** a parallel line,we have developed a multi-channel,broadband,low-noise,portable data acquisition system suitable for receiving skywave *** the skywave field excited by a high-power fixed source located in central China,actual field surveys have been carried out in some areas in China including the Biyang depression of Henan *** initial results appear encouraging—the interpreted resistivity models prove to be consistent with those of seismic exploration and known geological information,and the exploration cost is only～1/4 to 1/10 that of seismic *** initial successful applications of the skywave theory lay a solid foundation for further verification of the new method.
