Research on Calibration Method of Magnetic Sensor in Hybrid-Source Magneto Tellurics

摘要：

To obtain sensor sensitivity to the real weakmagnetic field intensity in field so that it can be used in Hybrid-source Magneto Tellurics, a kind of indoor calibration method of magnetic sensor is introduced. In this paper, with calibration conditions being satisfied, a calibration system was designed and results error was analysised. Because of the power-line disturbing, magnetic shielding and its influence to the calibrating precision are introduced.
