| 英文摘要 | With strong adaptability, deep detection and good real timeliness, SATEM is suitable for observation in lakes, swamps, mountains and other areas with complex terrains. SATEM has a large amount of received data and high accuracy requirements. The traditional imaging method based on the ground resistivity calculation does not consider height, and the calculation of the imaging depth needs to be more accurate. It is important to carry out the high-precision and fast imaging research of SATEM for practical applications. According to the characteristics of the induced current distribution of the electrical source transmitter, the receiver set in the air and the two are not on the same plane, the paper proposes the resistivity imaging method of SATEM considering the differences between the horizontal and vertical induction current, the impact of height on the apparent resistivity. Firstly, the paper analyzes the distribution characteristics of the induced current, the spatial distribution and diffusion characteristics of each component of TEM field with an electrical source. Secondly, based on the analytical solution of the uniform half space magnetic field and the induced voltage, the apparent resistivity of the early, late and full period are defined. Finally, the imaging depths of transverse and longitudinal components are defined based on the analysis of the induced current distribution, and the effects of the imaging depths by flight height, emitted magnetic moment, offset distance, and offset angle are investigated; the results of the actual measurements on the coal mining area show that the target position can be more precisely located using the resistivity imaging method proposed in this paper. |
