| 英文摘要 | Combining the advantages of ground electromagnetic and airborne electromagnetic method, the semi-airborne transient electromagnetic method can reach the balance between detection depth and working efficiency. Normally, the electromagnetic field excited by a single line source can only identify the geological body from one side, and is difficult to acquire the full image of the subsurface geologic body. Adopting multi-radiation sources is the way to solve this problem. The three-dimensional vector finite element method is used to perform forward of the electromagnetic response for two geological bodies under multi-radiation sources, and analyze the response distribution of the electromagnetic field from different sources at different flight altitudes. Results show that the multi-radiation sources can enhance the radiation intensity of the electromagnetic field, reduce the volume effect of the single-line electrical source, and obtain a strong response amplitude at a low flight height, which provides a theoretical basis for the fine detection using the multi-radiation source semi-airborne transient electromagnetic method. |
