半航空频率域电磁法二维正反演研究
2D forward and inversion study of semi-airborne electromagnetic method in the frequency domain
摘要
Abstract
This paper presents a two-dimensional(2D)forward modeling algorithm and the Occam inversion algorithm for the frequency-domain semi-airborne electromagnetic method(SAEM).Forward modeling simulations were conducted for several typical models to investigate the influence of various parameters(such as resistivity,burial depth,and source position)on the vertical magnetic field component(Bz).Inversion studies were conducted on both flat and undulating terrain models to assess the impact of topographic factors on inversion results.The 2D model offers significant computational efficiency,reducing the complexity of calculations and data processing while providing rapid,accurate approximate results.This study offers valuable insights into the application of the semi-airborne electromagnetic method in complex terrains and provides a foundation for further research in related fields.关键词
