Abstract
A method and device by means of which an irrotational, sourceless vector field can be expressed by a number of physically reasonable basis vectors. In the method and device for processing a multi-channel measurement of magnetic fields of the present invention, measured signals can be unambiguously divided into signals of the irrotational, sourceless vector field that are caused by an interesting object or external interferences, as well as into a signal caused by the nonideality of the measuring device. The invention is based on the combining of two very fundamental mathematical regularities and applying in the processing of signal vectors of a multi-channel measuring device that measures an irrotational, sourceless vector field. The invention is based on the Maxwell's equations of an irrotational, sourceless vector field, as well as on the convergence characteristics of series developments.
