| 内容記述 | Characteristics of VLF-MT method have been described. Apparent resistivity and phase angle can be obtained from the observed electric and magnetic components of VLF waves. This method utilizes the electric and the magnetic components perpendicularly intersecting each other. The direction of an electric component of VLF signals is normally set to that of the transmitter. It is a conventional way of measurement. In order to reveal the position of underground object it is desirable to set the magnetic component to the direction of target, that is, the electric component is perpendicular to the underground target. The angle between the direction of transmission station and that of the measurement line is permitted up to 50 degrees if we can correct the electric and magnetic components. I define a new parameter, the pointing vector, using apparent resistivity and phase angle between electric and magnetic components. This parameter is effective to know the position of underground structure with a small range error. |
