水平电偶源频率电磁测深是采用水平接地电偶极子在地下激发电磁场,在地面上分别测量电场分量和磁场分量(也可测相应场分量的相位),以提取反映地质构造的信息。 不妨将地球看成导电半空间,以水平均 Horizontal dipole frequency electromagnetic sounding is the use of a horizontal ground electric dipole to excite the electromagnetic field in the ground and measure the electric and magnetic field components (and the phase of the corresponding field components, respectively) on the ground to extract information that reflects the geological formation. Think of the Earth as a conductive half-space, with average water levels
