Magnetometer signal sampling within time-domain EM transmitters and method |
摘要 |
A time-domain airborne electromagnetic (AEM) system (200) for measuring a signal related to a magnetic field during a survey. The AEM system includes a 5 transmitter coil system (202) configured to generate a primary electromagnetic field that penetrates into the earth; a receiver coil system (212) configured to record a secondary electromagnetic field generated by the earth as a response of the primary electromagnetic field; and a magnetometer sensor (220) located coplanar with the transmitter coil system (202) and configured to record signals related to an external 0 magnetic field. A sampling window (416) is associated with the magnetometer sensor (220) and the sampling window (416) is calculated based on (i) various functional windows (410, 412, 414) characterizing the magnetometer sensor and (ii) current pulses (402A, 402C) applied to the transmitter coil system during the survey.
