ABSTRACT:
A method for measuring a local magnetic signal by estimating and eliminating the effects of one or more remote magnetic noise sources is provided. The method relies on "tagging" the undesired noise component of the local measurement in such a way as to allow separation of the noise component from the total measurement. The method makes use of the measurement apparatus already in place and does not require additional sensing channels.
